EXPLORE THE SANTA CRUZ TREK IN HUARAZ 4 DAYS

The Santa Cruz Trek is the most iconic and popular mountain hike in the Cordillera Blanca in Peru, considered by many to be one of the most beautiful treks in the world. It is located in the Ancash region, within Huascarán National Park, a UNESCO World Heritage Site since 1985. This route traverses a breathtaking landscape that combines imposing snow-capped peaks exceeding 6,000 meters, intensely turquoise lagoons, glacial valleys carved by ancient glaciers, and unique Andean biodiversity that includes viscachas, condors, and a diverse array of high-altitude flora.

The trek connects two spectacular valleys: the Llanganuco Valley to the east and the Santa Cruz Valley to the west, offering hikers an immersive experience in the majesty of the Peruvian Andes. Throughout the journey, you can appreciate some of the most iconic mountains of the mountain range such as the imposing Alpamayo (once considered the most beautiful mountain in the world), Huascarán (the highest peak in Peru), Artesonraju, Pirámide, Taulliraju and Quitaraju, among others, making each day an unforgettable visual spectacle.

The total distance of the Santa Cruz Trek varies approximately between 45 and 52 kilometers, depending on the specific route taken and whether optional detours to additional viewpoints are included. The classic and most recommended duration to fully enjoy the experience is 4 days and 3 nights, allowing for a leisurely and safe walking pace, with enough time to appreciate the scenery, take photographs, and properly acclimatize to the altitude. This 4-day version distributes the effort evenly, with daily hikes of between 5 and 7 hours of actual walking.

However, there is also the option of completing the trek in 3 days and 2 nights for hikers in better physical condition and with more experience in high-altitude mountaineering, although this involves longer and more demanding days that can exceed 8 hours of hiking. Some extremely fit travelers even complete it in 2 days, but this option is not recommended for most visitors, as the physical exertion and lack of proper acclimatization can significantly increase the risk of altitude sickness and diminish the enjoyment of the scenery.

The Santa Cruz Trek is generally classified as moderately difficult, meaning it doesn’t require technical climbing skills or prior mountaineering experience, but it does demand a reasonable level of fitness and good preparation. The route follows well-defined and marked trails, without needing to cross technically challenging terrain such as glaciers or climbing areas, making it accessible to people with determination and basic training. The main difficulty lies not in the technical complexity, but in the physical endurance required to hike for several hours a day at high altitude.

The true challenge of the trek is cumulative: combining long days of hiking with a light pack (if you hire a muleteer), sleeping in cold camps, and the constant effort of breathing in a low-oxygen environment. For someone with a sedentary lifestyle, the trek can be very demanding, while someone accustomed to regular exercise and with prior mountain hiking experience will find it challenging but entirely achievable. The most important thing is to maintain a constant and slow pace, especially on the climbs, always listening to the body’s signals.

During the four days of the trek, hikers remain consistently above 3,500 meters above sea level, moving within an altitudinal range that varies approximately from 3,600 meters at the lowest points of the valley to 4,750 meters at the summit. This prolonged stay at high altitudes is precisely what makes proper acclimatization necessary, as the body works in hypoxic (low oxygen) conditions throughout the trek, which affects cardiovascular endurance and muscle recovery.

The highest point of the entire route is the famous Punta Unión pass, located at 4,750 meters (some sources place it at 4,760 m), and represents the peak of the hike in terms of both effort and visual reward. Reaching this pass on the morning of the second or third day (depending on the chosen route) is a moving experience, as it offers spectacular panoramic views of the surrounding snow-capped peaks. The ascent to Punta Unión is the most physically demanding part of the trek, with a considerable elevation gain that tests the hikers’ endurance and acclimatization.

The Santa Cruz Trek has a marked seasonality due to the climatic conditions of the Peruvian Andes, and the best time to do it is during the dry season, which runs from May to September. During these months, the days are mostly sunny and clear, the nights are cold but dry, and the probability of rain is minimal, guaranteeing trails in good condition and unobstructed views of the snow-capped peaks. It is precisely during these months that the influx of national and international tourists reaches its peak, so it is recommended to book the services of guides and muleteers in advance.

The months of April and October are considered transitional, with more variable weather that can alternate between sunny days and sudden rain showers, making the trek still possible but with some weather uncertainty. In contrast, the rainy season, which runs from November to March, presents significantly greater challenges: trails become muddy and slippery, rivers can swell, making crossings difficult, the risk of landslides and mudslides increases, and low clouds often obscure the most spectacular scenery. Trekking during these months requires more preparation, good-quality waterproof gear, and flexibility in your plans.

The most popular option for travelers to get from Lima to Huaraz is the interprovincial bus, which offers excellent value for money and allows you to enjoy the changing scenery along the way. Well-known companies like Cruz del Sur, Movil Bus, and Línea offer overnight services departing around 9:00 p.m. and arriving in Huaraz between 5:30 a.m. and 7:00 a.m. the following day, thus optimizing travel time. The journey takes approximately 8 hours and follows the Central Highway to La Oroya, then continues along the route that crosses the beautiful Pativilca Canyon, offering spectacular views at sunrise.

Air travel is an option, but it is limited and unreliable for planning with certainty. LATAM Airlines operates occasional flights from Lima to Comandante FAP Germán Arias Graziani Airport, located in Anta, just 25 minutes from Huaraz. However, this option is usually considerably more expensive than the bus, flights are not daily, and they can be canceled at short notice due to weather or technical reasons. For these reasons, most experienced travelers and backpackers opt for the overnight bus, which also allows them to save on a night’s accommodation in Lima.

Since 2026, all visits to the Santa Cruz Trek must be made through a travel agency authorized by the Peruvian Ministry of Tourism and the Ministry of the Environment. Hiring a travel agency offers significant advantages, especially for those without high-altitude mountaineering experience or who simply prefer a more comfortable experience. A tour includes a professional trekking guide (familiar with the route, its risks, and the best campsites), a cook who prepares hot and nutritious meals, and muleteers with their donkeys who carry most of the equipment. This allows you to hike with a light backpack of only 5-7 kg, enjoying the scenery more and reducing the risk of injury or exhaustion.

If you book an organized tour with a travel agency, prices range from US$600 to US$1,000 per person, depending on the agency’s reputation, the group size, the quality of the equipment, and the guide’s experience. More affordable agencies typically offer basic services with large groups, while more expensive ones guarantee certified guides, better meals, higher-quality tents, and more personalized attention. A reasonable price for a quality tour is around US$800, which includes a guide, cook, muleteers, all meals during the trek, camping equipment, and round-trip transportation from Huaraz.

A standard 4-day Santa Cruz Trek tour typically includes a range of services that greatly enhance the experience. First, it includes round-trip transportation from Huaraz to the trek’s starting and ending points, usually in private or shared vehicles arranged by the agency. It also includes the services of a professional trekking guide who speaks English and Spanish, a cook specializing in mountain cuisine, and muleteers with their donkeys who transport the group equipment (tents, cooking gear, food) and a personal bag of up to 8-10 kg per trekker.

Regarding equipment, the tour provides camping tents (generally for two people), a dining tent with a table and folding chairs for protection from wind and rain during meals, sleeping mats, and all necessary cooking equipment. Meals are fully provided during the trekking days, including nutritious breakfasts, hot lunches, complete dinners, and snacks such as fruit, cookies, and hot drinks (tea, coffee, hot chocolate). Many agencies also include a first-aid kit and, in some cases, an emergency horse in case a hiker is unable to continue due to health problems or exhaustion.

Sleeping bags and trekking poles are not usually included, although most agencies offer them for rent for an additional $25, depending on the quality of the equipment. Another important aspect is tipping for the local staff, a common and highly valued practice in Peruvian trekking culture. It is recommended to allocate between 50 and 100 soles in total to be divided among the guide, the cook, and the muleteers, depending on the quality of service received and the duration of the trek. Additionally, accommodation in Huaraz before and after the trek is the responsibility of the traveler, as are meals in the city and travel insurance, which, although not mandatory, is highly recommended to cover possible medical emergencies or evacuations.

To do the Santa Cruz Trek, it is essential to bring your original identity document, either your DNI (National Identity Document) for Peruvians or your passport for foreigners, as it will be requested at the entrance checkpoint to Huascarán National Park. It is advisable to also bring some photocopies of your passport just in case, although the original is the valid document for registration. Foreign citizens must ensure that their passport is valid for at least six months from the date of entry into Peru, although this is more relevant for general immigration control than specifically for the trek.

In addition to personal documents, you need your Huascarán National Park entrance ticket, which can be purchased at the access control points. This ticket is personal and non-transferable and must be kept with you throughout the trek due to possible random checks. No additional special permits or mandatory vaccinations are required to enter the park, although it is always recommended to be up-to-date with your basic vaccination schedule (tetanus, hepatitis) before any trip to remote areas.

Altitude sickness, known locally as soroche, is the physiological response of the human body to exposure to high altitudes where the partial pressure of oxygen is lower. Basically, when ascending above 2,500 meters, the air contains less oxygen by volume, forcing the body to work harder to oxygenate the blood and tissues. This situation causes a series of symptoms that can vary in intensity depending on individual susceptibility, the rate of ascent, and the degree of prior acclimatization.

The most common symptoms of altitude sickness include persistent headache, nausea or vomiting, dizziness and vertigo, unusual fatigue and general weakness, loss of appetite, difficulty falling asleep or restless sleep, and in more severe cases, shortness of breath even at rest. It is important to understand that these symptoms are not a matter of being in good or bad physical shape, but rather of how each individual body reacts to hypoxia. That’s why some very athletic people can suffer severely from altitude sickness, while others with less training tolerate it perfectly.

Altitude sickness prevention begins long before the trek starts, with proper gradual acclimatization in Huaraz and its surroundings. The universal recommendation is to spend at least two or three nights in the city (3,052 m) before undertaking any high-altitude hike, and during those days take acclimatization excursions to lagoons such as Wilcacocha (3,700 m), Churup (4,450 m), or the famous Laguna 69 (4,600 m). These shorter hikes allow the body to begin producing more red blood cells and gradually adapt to the lower oxygen availability, preparing it for the greater exertion of the trek.

During the trek, preventative measures are equally important: maintain a slow and steady pace, especially on ascents (the famous “platform pace” or slow but steady walk), stay hydrated by drinking small sips of water every 20-30 minutes, avoid heavy and fatty meals that hinder digestion, and refrain from consuming alcohol or tobacco. Coca leaf tea, an ancient Andean tradition, is very effective in relieving mild symptoms and is available at all campsites and restaurants. In case of moderate or severe symptoms, the only truly effective treatment is immediate descent to a lower altitude.

Although not mandatory for entering Huascarán National Park, travel insurance with coverage for high-altitude activities is highly recommended and could be considered almost essential for a worry-free Santa Cruz Trek. Good insurance should cover not only medical expenses for common illnesses or accidents, but specifically helicopter or ground vehicle evacuation from remote mountain areas, as well as rescue in case of emergency. These services, if needed without insurance, can cost tens of thousands of dollars, and their logistical organization is complex in the Andean terrain.

In addition to evacuation, it is important that the policy includes coverage for trip cancellation due to health reasons, lost luggage, and civil liability. Many international insurers specializing in adventure travel, such as World Nomads and SafetyWing, as well as local companies, offer specific plans for trekking in Peru that meet these requirements. When purchasing insurance, be sure to verify that the fine print explicitly includes coverage for activities up to 5,000 meters above sea level, which is the altitude range where the Santa Cruz Trek takes place.

In case of a minor injury such as sprains, blisters, or mild general malaise, the trekking guide is trained to provide basic first aid and make decisions about whether or not to continue the trek. Professional guides carry first-aid kits with essential medications, bandages, pain relievers, and wound care supplies. In cases of altitude sickness that do not improve with rest, the primary strategy is to descend to a lower altitude. For this, the emergency horse that usually accompanies organized groups is used, allowing the affected person to be transported while the others continue or also descend.

If the situation is more serious and requires professional medical attention or evacuation, the guide will activate emergency protocols by contacting the National Park authorities or their base in Huaraz. Depending on the location and severity, an evacuation on horseback to the nearest town (usually Cashapampa) can be arranged, and from there, a transfer by ambulance or private vehicle to a medical center in Huaraz or Yungay. In extremely serious cases, a helicopter evacuation can be requested, although this is complex to coordinate and extremely expensive without insurance.

The key to dressing appropriately for the Santa Cruz Trek is the layering system, which allows you to adapt to the abrupt temperature changes typical of the Andean mountains. The first layer, in contact with your skin, should be thermal clothing (preferably made of synthetic materials such as polyester or merino wool) that wicks away sweat and keeps your skin dry, avoiding cotton, which retains moisture and cools the body. The second layer is an insulating layer, such as a fleece or synthetic down jacket, which traps body heat. The third layer, essential for the Peruvian highlands, is a waterproof and windproof jacket that protects against rain, snow, and glacial winds.

In addition to layers for your torso, it’s essential to pack comfortable trekking pants (convertible shorts are practical), thermal underwear for chilly evenings, several pairs of wool or synthetic socks (never cotton), a wool hat for sleeping and for cold mornings, a cap or hat to protect yourself from the intense midday sun, lined gloves (and optionally waterproof gloves for extreme cold), and a buff or neck warmer to protect your face from the wind and sun. Remember that mountain weather can change drastically in a matter of minutes, so it’s better to pack too much than too little.

If you book with an agency, basic camping equipment (tents, sleeping mats, mess tent) is included, but there are personal items that each hiker must bring or rent independently. The sleeping bag is the most critical item for comfortable nights and should be designed for temperatures down to -10°C or even -15°C, as early mornings at high-altitude camps are extremely cold. Agencies in Huaraz rent good-quality sleeping bags for around 15-25 soles per day, and it’s advisable to check that they are clean and in good condition before accepting them.

Other necessary personal equipment includes a headlamp with spare batteries (essential for moving around the camp at night and during early mornings), adjustable trekking poles (which significantly reduce the impact on your knees, especially on descents), a small daypack (20-30 liters) for carrying water, a camera, layers of clothing, and snacks during the hike, and a waterproof bag or liner to protect your clothes inside the larger pack carried by the donkeys. It’s also useful to bring a cloth bag for dirty clothes and another for frequently used items.

However, there are some items you should bring from home for reasons of hygiene, comfort, or quality. Trekking boots are the most important item: they should already be broken in, worn before, and be reliable, as new rental boots can cause blisters and injuries. It’s also advisable to bring your own technical clothing (thermal underwear, socks, and a waterproof jacket) for hygiene and because size and fit are important. For the rest of your gear, renting in Huaraz is a practical and economical option that also supports the local economy.

Physical preparation for the Santa Cruz Trek should begin at least 6-8 weeks before the trip, combining cardiovascular exercise with specific strength training. Cardiovascular training is essential for building endurance and includes activities such as brisk walking uphill, running, swimming, cycling, or using stair climbers. Ideally, you should do at least 3-4 sessions per week of 45-60 minutes, gradually increasing the intensity. Hiking with positive elevation gain is especially beneficial, as it simulates the actual conditions of the trek.
Strength training should focus on the legs (squats, lunges, calf raises) and the core (abdominal and lower back exercises), which are the muscle groups most stressed during backpacking. It is also important to get used to walking in the shoes and backpack you will use on the trek to identify any potential chafing or discomfort before the trip. One aspect that is often neglected is preparation for the effort at altitude: although altitude cannot be simulated, conscious breathing and the slow but steady pace that will be needed in the mountains can be practiced.

Choosing the right footwear is probably the most important decision when preparing your gear for the Santa Cruz Trek. Mid- or high-cut trekking boots are recommended, with good grip rubber soles (like Vibram or similar), waterproof (with a Gore-Tex membrane), and with good ankle support to prevent sprains on uneven terrain. The boots should have enough room so that your toes don’t press against the toe box on descents, and they should be broken in several times to avoid blisters and chafing.
It’s not advisable to use trail running shoes or low-cut athletic shoes for this trek, as ankle support is important on rocky sections and the uneven terrain can cause injuries. High-altitude plastic boots are also unsuitable, as they are too rigid and heavy for this type of hike. During daily walks, it’s crucial to wear technical socks that wick away moisture and change your socks midday if possible to keep your feet dry and prevent blisters.

A typical day on the Santa Cruz Trek begins very early, around 6:00 a.m., when the cook or guide visits the tents offering a comforting cup of coca tea or hot mate to help wake up and energize the body. After this initial wake-up call, there is approximately an hour to collect personal gear, wash up (with cold water, be prepared!), and pack your day’s backpack while the cook prepares a full, hot breakfast, which usually includes oatmeal, pancakes, eggs, bread, and hot drinks. Breakfast is the most important meal of the day and provides the necessary energy for the hours of hiking.
Around 8:00 a.m., the group begins the day’s hike, with the guide setting the pace and pointing out points of interest. The hike lasts for approximately 3-4 hours before lunch, with short breaks to rest, hydrate, and take photos. At midday, a sheltered spot is sought for lunch, where the cook has already arrived (the donkeys are faster) and prepares a hot, three-course meal. After lunch, the group continues walking for another 2-3 hours to reach the night’s camp, where tents are set up, everyone rests, and has dinner around 6:30 p.m. Exhausted but happy, they then go to bed early, around 8:00 p.m.

The location of the campsites may vary slightly depending on the agency, the guide, and the group’s pace, but the classic itinerary (following the route from east to west, from Vaquería to Cashapampa) establishes three fixed campsites. The first night is spent camping at Paria, at 3,870 meters, a relatively sheltered spot with beautiful views of Huascarán. This first campsite serves as an introduction to high-altitude life and allows each person to assess how they cope with the night on the mountain.

The second night is spent at Taullipampa, at 4,250 meters, the highest and coldest campsite on the entire route, located in a valley surrounded by imposing snow-capped peaks such as Taulliraju and Rinrijirca. From here, the ascent to Punta Unión is usually undertaken the following day. The third night is spent at Llamacorral, at 3,760 meters, already descending towards Cashapampa, a warmer campsite with a more relaxed atmosphere, having already overcome the most demanding section. Some groups may camp in other areas such as Huaripampa or Ichiccocha depending on the circumstances.

The food on the Santa Cruz Trek, especially if you book through an agency, is usually surprisingly varied and plentiful, considering it’s prepared in mountain conditions using portable stoves. Andean cooks are famous for their skill in preparing delicious and nutritious dishes with fresh ingredients transported by donkeys. A typical breakfast might include hot porridge, pancakes with honey or jam, scrambled eggs, fresh bread, cheese, and a variety of hot drinks (tea, coffee, hot chocolate). Lunches are usually three-course meals: hot soup to start, a main course (such as arroz con pollo, lomo saltado, noodles, or quinoa with vegetables), and dessert or fresh fruit.

Dinners are also hearty and hot, generally soup followed by a substantial main course such as pasta, mashed potatoes with meat, or stews, and again, fruit or gelatin for dessert. During hikes, snacks such as fresh fruit (apples, bananas, oranges), cereal bars, cookies, candy, and nuts are provided. Boiled or filtered water is available at all meals, and it is customary for the cook to offer hot tea in the tent in the morning to help you wake up. Vegetarian, vegan, or allergy-conscious hikers should notify the agency in advance so that suitable options can be prepared.

Access to water during the Santa Cruz Trek is not a problem, as the route runs parallel to crystal-clear rivers and streams fed by meltwater. However, the water is not directly potable and must be treated before consumption to avoid gastrointestinal illnesses that could ruin the experience. Mountain waters, even if they appear clean, can contain bacteria, parasites, or viruses from wildlife or human activity upstream, so it is essential to purify them using a reliable method.

Options for purifying water include boiling it for at least 5 minutes (which is what tour operators do for meals and to fill trekkers’ thermoses), using water purification tablets (such as Micropur or similar, available at pharmacies in Huaraz), using portable water filters like “life straws” or pump filters, or using iodine or chlorine drops (less recommended due to the taste). If you’re traveling with a tour operator, they usually provide cooled boiled water at the campsites, but during the day’s hike, everyone should carry their own water and have a way to refill it at streams. Bringing a reusable bottle is much better than buying disposable plastic bottles.

Cell phone coverage on the Santa Cruz Trek is practically nonexistent for most of the route, especially in the deep valleys and at high-altitude campsites. Only at very high and specific points, such as the summit of Punta Unión or on some slopes with a clear view towards Huaraz, can you get a weak signal from a carrier (usually Claro or Movistar), but it’s not reliable. This digital disconnection is precisely one of the trek’s attractions, as it allows you to completely isolate yourself from the outside world and immerse yourself in nature.

Regarding electricity, there are no charging points at the campsites, so it’s necessary to bring all your electronic equipment with enough batteries for the 4 days. It’s recommended to bring a high-capacity power bank (at least 10,000-20,000 mAh) to charge your phone and camera, and to activate power-saving mode on your devices. DSLR cameras may need spare batteries, as the cold at night accelerates battery drain. Ideally, use your phone only for taking photos and turn it off or put it in airplane mode the rest of the time to conserve battery life.

For the Santa Cruz Trek, it’s essential to carry enough cash in Peruvian soles, as there are no ATMs or card payment options along the route. The necessary cash should cover several expenses: the National Park entrance fee (60 soles), tips for the guide, cook, and muleteers (between 50 and 100 soles total), any snacks or drinks you might want to buy at the occasional (and infrequent) stalls, and return transportation from the end point if it’s not included. It’s also advisable to bring extra money for unexpected expenses.

In total, someone traveling with an agency should carry between 200 and 300 soles in cash (approximately US$50-80) to cover these additional costs. If you’re traveling independently, the amount needed is higher, as you’ll have to pay for round-trip transportation (around 60-80 soles total), buy food in Huaraz before the trek (approximately 100 soles), and rent equipment if necessary. It’s advisable to carry small bills and coins to facilitate payments, as checkpoints and communities don’t usually have change for large bills. US dollars are not accepted in these places; only the local currency is accepted.

The growing number of visitors to the Santa Cruz Trek has a significant environmental impact on this fragile high-mountain ecosystem. The main problems are solid waste generation, water source pollution, trail erosion from constant trampling, and disturbance of wildlife. For this reason, it is the responsibility of every hiker to adopt low-impact practices and follow the “Leave No Trace” principles, which are especially important in a protected area like Huascarán National Park.

To minimize your impact, please follow these practices: take all your trash back to Huaraz (including paper, food scraps, and hygiene products), avoid single-color plastics and bring reusable bottles, use the restrooms at campsites or, if unavailable, bury your waste deep enough (at least 30 cm) and away from water sources, do not wash clothes or utensils directly in rivers or lakes, stay on marked trails to avoid soil erosion, do not feed or disturb wildlife, and respect the peace and quiet of other hikers by avoiding unnecessary noise. Small individual actions, when combined, can preserve this Andean paradise for future generations.
