The Santa Cruz Trek is a three- to four-day high-altitude hike in the Cordillera Blanca of Peru, crossing part of Huascarán National Park between the trailheads of Vaquería and Cashapampa. The route is normally walked as a camping trek, with access and return transport arranged through Huaraz, Yungay and Caraz. It follows glacial valleys, lakes and streams beneath some of Peru's most famous peaks, including Taulliraju, Alpamayo, Artesonraju and Huascarán.

The classic route is about 50 km (31 mi) long and crosses 4,750 m (15,580 ft) Punta Unión pass. Most hikers complete it in four days and three nights, although acclimatized and fit hikers sometimes do it in three days. The trek can be walked independently or with a guide, cook and pack animals arranged through agencies in Huaraz.

Understand

The Santa Cruz Trek is one of the most popular treks in the Cordillera Blanca because it combines relatively straightforward trail walking with close views of high Andean scenery. It crosses Quebrada Huaripampa and Quebrada Santa Cruz, two glacial valleys separated by Punta Unión. From the pass there are views toward Taulliraju, and from the western side of the route there are views toward Alpamayo, Artesonraju, Rinrihirca, Quitaraju and other peaks.

The route lies within Huascarán National Park, a protected area covering much of the Cordillera Blanca. The landscape includes puna grassland, glacial lakes, high wetlands, moraines, streams and snow peaks. Quechua-speaking farming and herding communities live around the approaches to the trail, especially on the Vaquería side, and hikers may meet local people, pack animals, cattle and donkeys on the route.

The trek does not require technical mountaineering skills, but it is a serious high-altitude hike. The highest point is 4,750 m (15,580 ft), and most camps are around 3,800 m (12,500 ft)–4,300 m (14,100 ft). Hikers should be comfortable walking several hours a day while carrying a pack, should know how to camp in cold mountain conditions, and should be acclimatized before starting. Spending a few days in Huaraz and doing one or two acclimatization hikes, such as Laguna Churup or Laguna 69, is strongly recommended.

The hike may be done in either direction: Vaquería to Cashapampa or Cashapampa to Vaquería. Vaquería to Cashapampa is often preferred because it starts higher, crosses Punta Unión earlier in the trek and finishes with easier return transport from Cashapampa through Caraz. Cashapampa to Vaquería has a more gradual ascent to the pass, but starts lower and may feel hotter and drier on the first day.

Prepare

You must pay the Huascarán National Park entry fee. Keep the ticket with you, as there are park checkpoints and rangers may ask to see it. Drivers of colectivos or minibuses may not always stop automatically at the correct park office, so remind the driver if you still need to buy or validate your ticket.

Some SERNANP visitor information says that visitors should use authorised operators in Huascarán National Park. Independent trekking has historically been common on the Santa Cruz route, but rules and enforcement can change. Check the current situation with SERNANP, the park office or a reliable agency in Huaraz before setting off.

Bring a GPS device or phone with offline maps, plus a backup power bank. The route is reasonably well marked and there are signs at important junctions, but poor weather or side trails can make navigation confusing. OpenStreetMap has good coverage of the area, OpenAndroMaps has offline vector maps for Peru, and topographic trekking maps can usually be bought in Huaraz.

Independent hikers need a tent, warm sleeping bag, sleeping mat, stove, fuel, water treatment, food for the whole trek, rain gear, warm layers, sun protection, headlamp and first-aid supplies. Nights can be below freezing, especially in the dry season, so a sleeping bag rated to at least around -5°C is sensible; colder sleepers may want a warmer bag. Agencies in Huaraz rent equipment, although quality varies.

Pack animals and arrieros can be hired through agencies or sometimes in villages near the trailheads. If using donkeys or horses, confirm what is included, the weight allowance, whether the arriero stays with you for the full route, and where the animals will meet you each day. Without pack animals, you must carry all camping equipment and food yourself.

The trail is a mountain footpath. It is not suitable for baby carriages, wheelchairs, carts or wheeled luggage. There are rocky sections, muddy wetlands, stream crossings, steep climbs and high-altitude camps.

Eat

There are no shops or restaurants on the trek itself. Buy food in Huaraz, Caraz or Yungay before starting. If going independently, carry all meals, snacks, stove fuel and cooking equipment. Open fires are prohibited in the national park, so use a camping stove.

Guided treks usually include meals, cooking equipment and a cook, but not always snacks, drinks outside meals, breakfast on the first day or lunch on the final day. Check the details before paying.

Drink

Streams and lakes are common along most of the route, except near Punta Unión where water may be limited. Carry enough water for the climb to and descent from the pass. Because livestock graze throughout the valleys, treat all wild water before drinking it. A filter, chlorine dioxide tablets, iodine or boiling are all suitable methods; many hikers combine filtration with chemical treatment.

Do not rely on buying bottled water once on the trail. Carry reusable bottles or a hydration bladder and avoid disposable plastic.

Sleep

The Santa Cruz Trek is normally a camping itinerary. There are designated campsites along the route, and hikers should use them to reduce erosion and damage to fragile highland vegetation. There are no staffed mountain huts on the classic route.

The usual camps, listed from Vaquería to Cashapampa, are Paria, Taullipampa and Llamacorral. Ahruaycocha, near Alpamayo base camp, is often used for a side trip or by hikers taking a slower itinerary. Campsites are basic; expect flat camping areas, water nearby and sometimes simple toilets, but no electricity, showers or shelter.

Accommodation is available before or after the trek in Huaraz, Caraz, Yungay and some trailhead villages. Reservations are useful in the high season, especially for Huaraz hostels and hotels.

Climate

The best season is the dry season, roughly May to September or October. Days are usually clearer, but nights are cold and frost is common. The rainy season, roughly October to April, brings cloud, rain, hail, muddy trails and a higher risk of poor visibility at Punta Unión. The trek is possible outside the main season, but weather can make it much less pleasant and more hazardous.

At high altitude, strong sun, wind, rain and cold can all occur on the same day. Bring sunscreen, sunglasses, a brimmed hat, waterproof jacket and trousers, gloves, warm hat and insulating layers.

Environment

The trek passes through a protected national park. Stay on marked trails, camp only in established areas, pack out all rubbish, avoid single-use plastics, and do not wash with soap directly in streams or lakes. Use toilets where provided; otherwise bury human waste well away from watercourses and camps.

Do not pick plants, disturb wildlife or feed animals. Brush mud and seeds from boots, tent pegs and equipment before entering the park and after leaving it, especially if you have recently hiked in other regions, to reduce the spread of invasive seeds and soil-borne organisms. Keep food secure from cattle, donkeys and other animals.

Get in

Most hikers arrange transport in Huaraz, the main trekking hub for the Cordillera Blanca. Agencies offer guided group departures, private transport and sometimes spare seats in vehicles already going to a trailhead.

For an all-inclusive trip, book with one of the travel agencies in Huaraz. Typical packages include transport, guide, cook, tents, meals and pack animals, but usually exclude the national park entry fee, personal equipment, snacks and tips. Cheaper tours may have older gear or larger groups; more expensive tours may include better tents, hot drinks, warmer sleeping bags or a higher baggage allowance.

For independent travel, ask agencies whether they have spare space in a vehicle going to Vaquería or Cashapampa. If a group is already running, spare seats may be inexpensive. Private transport is more costly but simpler, especially for an early start.

• Vaquería: From Huaraz, take early transport north to Yungay, then continue through the Llanganuco road and over the high road toward Yanama, getting off at Vaquería. In practice this may require a colectivo to Yungay and another colectivo, combi or minibus toward Yanama. Services are limited and usually leave early in the morning, so check locally the day before. The road passes the Llanganuco lakes and reaches high altitude before descending toward Vaquería.

• Cashapampa: From Huaraz, take transport to Caraz, then a colectivo or taxi to Cashapampa. Public transport to Cashapampa may be irregular, so it is common to use a shared or private taxi from Caraz. Cashapampa is the easier trailhead for returning to Huaraz after finishing the trek from Vaquería.

Walk

The following description gives the common four-day route from Vaquería to Cashapampa. Distances and times are approximate and vary with campsites, weather, acclimatization and side trips. The route can also be walked in reverse.

Vaquería to Paria

 11 km 4–5 hr 450 m

From 1 Vaquería, the trail descends and then follows the Huaripampa valley through small settlements, fields and grazing areas. This is the most inhabited part of the trek, with views of traditional houses, livestock and cultivated plots. The walking is usually moderate, though the altitude is already high.

The route gradually leaves the villages and enters more open valley scenery. Continue toward the designated campsite at Paria, a broad camping area near water and below the higher mountains leading toward Punta Unión.

• 1 Paria. Common first-night campsite when walking from Vaquería to Cashapampa. Basic camping area with water nearby. Treat all water before drinking. 

Paria to Taullipampa via Punta Unión

 13 km 6–8 hr 900 m

This is usually the hardest and most spectacular day of the trek. From Paria, continue up the valley toward the head of Quebrada Huaripampa. The trail climbs steadily through increasingly alpine terrain, passing streams, wetlands and moraine slopes. The final ascent to Punta Unión is steeper and rockier, and can be tiring because of the altitude.

1 Punta Unión is the high point of the trek at about 4,750 m (15,580 ft). In clear weather there are excellent views back down Quebrada Huaripampa and west into Quebrada Santa Cruz, with Taulliraju rising above the pass. Do not linger too long in bad weather, as the pass is exposed to wind, hail, snow and lightning.

Descend carefully on the western side. If the rocks are wet or icy, this section can be slippery. The trail eventually reaches the valley floor and continues toward Taullipampa, one of the most scenic camps on the route, with views toward Taulliraju and surrounding peaks.

• 2 Taullipampa (Taulipampa). Common second-night campsite when walking from Vaquería. A scenic high camp below Taulliraju. Nights can be very cold. Treat water before drinking. 

Taullipampa to Llamacorral

 13 km 4–5 hr 100 m

From Taullipampa, the main trail descends gradually through Quebrada Santa Cruz. This stage has some of the best mountain views of the trek, including the side valleys leading toward Alpamayo and Artesonraju. The walking is generally easier than the Punta Unión crossing, although the day can become long if you include the side trip to Alpamayo base camp or Laguna Arhuaycocha.

A popular optional side trip climbs north from the main valley toward 2 Laguna Arhuaycocha and Alpamayo base camp. Allow about 2–3 extra hours return from the main trail, with roughly 350 m (1,150 ft) additional cumulative ascent. The detour gives closer views into the Alpamayo area and is worthwhile in clear weather, but it adds time and effort. Leave large packs at camp or with your group only if you can do so securely.

Continue down the main valley past glacial lakes and open grazing areas toward Llamacorral, the usual final campsite before Cashapampa.

• 3 Ahruaycocha (Arhuaycocha; Alpamayo Base Camp) (side valley north of the main Santa Cruz trail). Camping area and side-trip destination near Alpamayo base camp. Usually visited as an optional detour from the Taullipampa–Llamacorral stage, or as an additional camp on a slower itinerary. The detour adds ascent and time. 
• 4 Llamacorral. Common final-night campsite when walking from Vaquería to Cashapampa. Basic camping area with water nearby. Watch food and gear around livestock. 

Llamacorral to Cashapampa

 10 km 3–4 hr 50 m

The final stage follows Quebrada Santa Cruz westward, descending into a warmer and drier valley. The trail is generally clear, but can be dusty, rocky and hot in the lower section. Start early if you want to avoid the strongest sun and reach onward transport in good time.

The trek ends at 2 Cashapampa, a village roadhead with occasional taxis and colectivos to Caraz. Transport is more frequent earlier in the day and in the main trekking season; otherwise you may need to wait, share a taxi with other hikers or arrange pickup in advance.

Stay safe

Altitude is the main hazard. Do not start the trek immediately after arriving from sea level. Symptoms such as headache, nausea, dizziness, loss of appetite or unusual fatigue may indicate altitude sickness. Descend if symptoms worsen, and do not cross Punta Unión with severe symptoms.

Weather can change suddenly at high altitude. Carry warm and waterproof clothing even if the morning is clear. Avoid exposed high ground during thunderstorms, and be cautious on the pass in snow, hail or poor visibility.

Stream crossings, wet rocks and muddy sections can be slippery, especially during or after rain. The eastern side of Punta Unión has steep rocky sections and large drops in places, so take extra care in bad conditions.

Livestock are common. Step to the uphill side of the trail when donkeys, horses, llamas or cattle pass. Keep food inside your tent or otherwise secured; cattle may chew or eat unattended food, clothing, shoes and packs.

Mobile phone coverage is unreliable or absent for much of the route. Tell someone your plan before leaving Huaraz, carry a first-aid kit and consider travel insurance that covers high-altitude trekking and evacuation.

Go next

From Cashapampa, take a colectivo or taxi to Caraz, then onward transport to Huaraz. If walking the route in reverse, return from Vaquería toward Yungay and Huaraz by colectivo, minibus or pre-arranged transport, keeping in mind that services are limited and often leave early.

After the trek, many travellers rest in Huaraz or Caraz. Good onward options include Laguna 69, Laguna Parón, Laguna Churup, the Pastoruri Glacier area, climbing or trekking around Nevado Pisco, or the longer Huayhuash Circuit for experienced and well-acclimatized hikers.
