Climb to the rim of Lascar—Atacama’s active volcano—and watch sunrise light the lagoon and crater in a breathless sweep. This full‑day, high‑altitude hike demands acclimatization but rewards with stark volcanic panoramas and a dramatic dawn over Laguna Lejía.

Before dawn the Atacama sky hardens into a sheet of stars and the silhouette of Lascar rises like a dark promise on the horizon. Small groups depart San Pedro de Atacama in the black, crossing salt flats until the road narrows and the desert wind begins to push. By the time the party reaches Laguna Lejía, the horizon has already brightened; the crater’s rim takes on a sudden, raw clarity as the first light hits volcanic rock and fumarole steam.

Fitness Level
Participants should be in good aerobic shape and acclimatized to high altitude; regular hikers with prior altitude experience are best prepared.
Wildlife
History
Lascar is the most active volcano in the Atacama region; its eruptions and fumarolic activity have shaped local landforms and influenced traditional highland travel routes.
Conservation
The high desert is ecologically fragile—stay on established tracks, pack out waste and respect seasonal bird and mammal habitats around the lagoons.
Reserve your spot on the Lascar Volcano 5,592 m.a.s.l. today and enjoy a trusted, highly rated experience designed to help you make the most of your adventure.
Acclimatize before you go
Spend 24–48 hours in San Pedro de Atacama to reduce altitude sickness risk; avoid heavy exertion the day before the climb.
Hydrate and carry calories
Bring 2–3 liters of water and high‑energy snacks—altitude increases dehydration and calories burn faster.
Use trekking poles
Poles improve balance on loose volcanic scree and reduce strain on knees during the steep descent.
Dress for rapid temperature swings
Layer a windproof shell over insulating midlayers—temperatures drop quickly after sunset and morning winds are strong.
Layered insulation (base, mid, shell)
Protects against wind and rapid temperature changes at high elevation.
Sturdy waterproof hiking boots
Support and traction on loose volcanic scree and uneven terrain.
Trekking poles
Improves stability uphill and reduces impact on knees during descent.
Hydration system (2–3 L) and electrolyte tablets
Maintains hydration and electrolyte balance in the dry, high‑altitude desert.
