Climb to the summit of Lascar, the Atacama’s most active volcano: a high-altitude trek that gains 600 m in under 5 km, begins at Laguna Lejía and delivers raw volcanic panoramas. Expect thin air, stark views and a full-day, 9–11 hour outing.

Dawn breaks over the salt-scrub highlands and the bus drops the group at Laguna Lejía (4,325 m). The lake's flat surface holds a cold light while Lascar, Pili and Sinbad volcanoes stand like stern judges on the horizon. Guides hand out poles and helmets, everyone tightens layers, and the climb begins southeast toward the steaming cone.

Conservation
The high-altitude desert is ecologically fragile — stick to trails, pack out waste and minimize disturbance to sensitive soils and wildlife.
Reserve your spot on the Lascar Volcano Trekking today and enjoy a trusted, highly rated experience designed to help you make the most of your adventure.
Acclimatize first
Spend 24–48 hours in San Pedro de Atacama to reduce altitude sickness risk before attempting the ascent.
Carry 3+ liters of water
High altitude and desert sun dehydrate quickly — sip frequently rather than waiting until you’re thirsty.
Dress in layers
Temperatures swing from freezing at the summit to mild on the trail; base, insulating and windproof layers are critical.
Pace your breathing
Take steady, measured steps and focus on slow breaths to manage exertion above 4,000 m.
Sturdy waterproof trekking boots
Support and traction on loose volcanic scree and uneven trails.
Three-layer clothing system (base, insulating, windproof)
Keeps you warm at the summit and lets you shed heat during the trek.
3+ liters water and electrolyte mix
Prevents dehydration in the dry high-altitude air.
High-SPF sunscreen, sunglasses and hat
The Atacama’s high sun exposure makes sun protection indispensable.
