A guided, high-altitude ascent of Cerro Toco (5,600 m) offers a brisk climb from a 5,200 m trailhead with panoramic views of Licancabur, Sairecabur and the Bolivian altiplano. Expect a 2–2.5 hour climb, strong winds, and the need to be acclimatized before the outing.

A thin, clean light breaks over the Altiplano as your van climbs out of San Pedro de Atacama and the peaks push into view. The wind has a voice up here — blunt, cold, and honest — and it will test your layering and your pace long before the summit does. You step off at roughly 5,200 meters, shoulders squared to a slope of gravel and volcanic scree. The ascent is straightforward but relentless; each switchback begs you to breathe slower and trust your legs.

5 hours
Fitness Level
Good aerobic fitness and prior high-altitude trekking experience recommended; must be acclimatized to avoid altitude illness.
Wildlife
History
Cerro Toco is part of the Central Volcanic Zone of the Andes; volcanic cones here record successive eruptions and uplift tied to subduction along the Pacific margin.
Conservation
Visitors should stick to existing paths, pack out all waste, and minimize disturbance to fragile high-elevation vegetation and archaeological traces.
Reserve your spot on the Ascent to the extinct Cerro Toco Volcano at 5600 meters high today and enjoy a trusted, highly rated experience designed to help you make the most of your adventure.
Acclimatize before the climb
Spend 48–72 hours in San Pedro de Atacama at moderate activity to reduce altitude sickness risk; hydrate and avoid heavy alcohol.
Pace for thin air
Keep your effort steady — short, frequent breaks and controlled breathing beat fast, aggressive moves at >5,000 m.
Sun protection is mandatory
High-altitude sun is intense; broad-spectrum SPF, lip protection, and glacier sunglasses are necessary even on cloudy days.
Use trekking poles on scree
Poles or the provided canes improve balance on loose volcanic gravel during ascent and descent.
Insulated shell and mid-layer
Lightweight down or synthetic jacket and a windproof shell for sudden cold and wind at the summit.
Sturdy hiking boots (ankle support)
Firm traction and ankle support help on loose volcanic scree and rocky approaches.
High-SPF sunscreen and glacier sunglasses
Protects skin and eyes from intense UV at elevation and reflective salt flats below.
Trekking poles or collapsible cane
Reduces strain on knees during descent and assists balance on steep, loose slopes.
