Tucked into the heart of the Cordillera Blanca, the Santa Cruz Trek showcases some of the most dramatic mountain scenery in South America. The route threads between ice-clad summits, alpine lakes and verdant valleys, making it a favourite among photographers and hikers alike. It’s also relatively accessible and can be completed in as little as three days with proper acclimatization.

Route & Itinerary

The classic west-to-east route stretches for about 54 km (34 mi). Starting at the village of Cashapampa, Day 1 follows the Santa Cruz River into a narrow gorge, climbing gradually to the camp at Llamacorral. Day 2 continues up the valley past Laguna Jatuncocha and spectacular peaks like Quitaraju and Alpamayo to the campsite at Taullipampa. On Day 3 you ascend switchbacks to Punta Unión pass at 4,750 m (15,584 ft), enjoying views of the surrounding peaks before descending into the Huaripampa valley. Day 4 is a gentle walk to Vaquería where transport back to the town of Huaraz awaits. Many trekkers add a side trip to turquoise Laguna 69 either before or after the trek.

Highlights

  • Crossing Punta Unión and soaking in unobstructed vistas of towering snow-capped peaks.
  • Camping near alpine lakes that reflect sunsets and starry skies.
  • Encountering Andean flora such as puya raimondii (giant bromeliads) and colourful lupines.
  • Optional detour to Laguna 69, one of Peru’s most photogenic lakes.

Difficulty & Preparation

The Santa Cruz Trek is graded as moderate. Although the distances are reasonable and the trails well marked, the elevation is significant and trekkers must cross a 4,750-m pass. Spend several days acclimatizing in Huaraz or surrounding villages and consider a short day hike beforehand. Pack animals are typically hired to carry tents and food, allowing hikers to travel with a light day pack.

Weather & Safety

Weather in the Cordillera Blanca can change rapidly. Afternoon thunderstorms are common even in the dry season. Always carry rain gear and a warm layer. Check trail conditions with park rangers before you go, and avoid trekking in the wet season (December – March) due to landslides.

Best Time to Trek

The dry winter months of May to September offer the best chances for clear skies and stable conditions. Temperatures drop below freezing at night, so a good sleeping bag is essential. In the wet season, heavy rains may wash out sections of the trail and obscure mountain views.

Planning Tips

The trek lies within Huascarán National Park, which charges a small entrance fee. Hire licensed guides and muleteers from local communities to support the park’s conservation efforts. Bring a water filter or purification tablets, avoid single-use plastics and follow Leave No Trace principles to help preserve this fragile environment.
