The Experience

You arrive where wind-carved towers of volcanic rock rise like an old quarry, their ribs and hollows daring your fingertips as the high puna stretches away toward the Cordillera Blanca. At roughly 4,200 meters the air is thin and crisp; sheep graze on flattened tussocks while peaks cut the horizon, and the rock forest’s honeycombed faces invite both careful climbers and curious walkers.

Before You Go

Acclimatize in Huaraz first

Spend a day in Huaraz to adjust to altitude—headache and fatigue are common without acclimatization.

Bring plenty of water

High altitude and sun make hydration critical; carry at least 2–3 liters per person for the day.

Sturdy footwear for scree

Wear stiff-soled hiking boots to handle loose rock and short climbs safely.

Sun protection and warm layers

Sun is intense at this elevation by day; temperatures can drop quickly—pack a sun hat, sunscreen and an insulated jacket.
