Before sunrise the altiplano sighs cold and wide. You roll out of San Pedro de Atacama while the Jeep stirs gravel into a silver morning; red-brown volcanoes rear up as the road climbs and the air thins. By the time you reach Laguna Lejía the lake’s pale crust and glassy shallows reflect an Andes sky so clear it feels sharp to the eyes.
Difficulty
moderate
Duration
7–8 hours
Fitness Level
Moderate fitness recommended; ability to walk short distances at high altitude, and to tolerate thin air and cold.
Wildlife
History
Cerro Overo is a postglacial maar formed by phreatomagmatic eruptions; the region’s highland wetlands have long supported indigenous pastoral practices.
Conservation
High Andean wetlands are ecologically fragile—stay on designated routes, avoid disturbing flamingos, and pack out waste to protect breeding and feeding areas.

Acclimatize in town first
Spend 24–48 hours in San Pedro de Atacama before the trip to reduce risk of altitude sickness at ~4,000 m.
Carry at least 2–3 liters of water
High altitude and strong sun increase dehydration—sip steadily rather than waiting until thirsty.
Sun and wind protection
Bring SPF 50, sunglasses, and a windproof outer layer—UV and desiccating winds are intense even on cool days.
Bring a telephoto and patience
Wildlife like flamingos and foxes are best observed from a respectful distance; a 200mm+ lens helps capture details.
Water (2–3 L)
Hydration is critical at altitude and in dry desert air.
Sturdy hiking boots
Rugged, supportive footwear handles uneven, salty flats and volcanic scree.
Layered clothing with windproof shell
Temperatures swing from icy mornings to strong sun—layers trap heat and shed wind.
Sun protection & sunglasses
High UV at elevation makes sunscreen, a wide-brim hat, and quality sunglasses essential.
