A thin air hush settles as you step off the minivan onto the puna near the Carpa sector of Huascarán National Park. Wind combs the short grasses; distant peaks cut the sky. The walk to Pastoruri Glacier is short—about 2 km and roughly 45 minutes on a rocky, sometimes loose trail—but every step climbs toward a living record of change.

Acclimatize before you go
Spend 24–48 hours in Huaraz to reduce altitude sickness risk—slow pace and light activity the day before are essential.
Sun at altitude is intense
Bring high‑SPF sunscreen, wide‑brim hat, and UV sunglasses; snow and pale rock reflect sunlight strongly.
Hydration and small snacks
Carry at least 1.5–2 liters of water and electrolyte snacks; dehydration worsens altitude symptoms.
Consider the horseback option
Local communities offer horses for part of the walk; useful if you want to reduce uphill time but still arrive high on the glacier.
Insulated wind shell
Lightweight warmth and wind protection are crucial above 4,500 m when conditions change quickly.
winter
Sturdy hiking boots
Support and traction on loose scree and rocky trail reduce slipping on the ascent.
High‑SPF sunscreen & sunglasses
Protect skin and eyes from intense UV at high elevation and reflective surfaces.
summer
Water bladder or bottles (1.5–2 L)
Maintain hydration to help prevent altitude sickness and keep energy steady.
