An 8-day loop around Peru’s Cordillera Huayhuash—one of South America’s steepest, most dramatic mountain circuits. Expect multiple 4,300–5,100 m passes, remote camps beside turquoise lakes, and sustained high-altitude hiking that rewards preparation.
More ways to explore the area's outdoor wonders
You wake before dawn to a cold, thin light and the sound of burros shifting gear—this is the Cordillera Huayhuash, a compact, uncompromising spine of granite and ice where passes routinely top 4,500–5,000 meters. On the first day the road closes behind you; over the next week the range presses in: jagged ridgelines, glacial bowls, and lakes the color of struck metal.

Acclimatize in Huaraz first
Spend at least 48–72 hours in Huaraz before the trek to reduce acute altitude effects and test your gear on shorter day hikes.
Layer for wide temperature swings
Bring breathable base layers plus an insulated jacket and wind shell—nights are cold and afternoons can be warm in sun-exposed sections.
Use trekking poles
Poles reduce knee strain on long descents and improve balance on rocky scree and uneven high passes.
Protect from strong sun
High UV at altitude means broad-spectrum sunscreen, a wide-brim hat and UV sunglasses are non-negotiable.
Insulated down jacket
Lightweight warmth for cold camps and windy passes.
Sturdy waterproof hiking boots
Support and protection on rocky ascents, moraine and occasional wet ground.
Sleeping bag rated to -10°C (14°F)
Nights at 4,000+ m can drop well below freezing—sleeping bag provided by many operators but bring your own if possible.
Trekking poles
Stabilize descents, reduce joint load and help on loose scree.
