Ruta de las Lagunas Altiplanicas
Andean lagoon circuit above the clouds
This high-altitude route threads through the remote Antofagasta highlands, connecting a chain of pristine lagoons via abandoned copper mining access roads and pre-Columbian trade paths. The track climbs steadily from Calama through increasingly barren volcanic terrain, crossing the stark Salar de Ascotán before reaching Laguna Lejía at 4,300 meters, where flamingos feed against a backdrop of snow-capped volcanoes. The route continues northeast past Laguna Miñiques and through the challenging Paso de Toco, where loose volcanic scree and altitude demand respect.
Rated Difficult due to extreme altitude, technical rocky sections, and complete isolation. High-clearance 4WD essential, along with extra fuel, water, and altitude sickness precautions. Best tackled May through September when weather is stable. No services for 200+ kilometers, making this a true backcountry commitment. The payoff is witnessing some of Chile’s most pristine altiplano wilderness, with world-class stargazing and encounters with vicuñas and Andean flamingos in their natural habitat.

Frequently asked questions
Can a stock Hilux or 4Runner handle this route, or do I need a built rig?
A stock high-clearance 4WD will get through, but expect soft volcanic sand, rocky two-tracks, and river crossings that will punish anything lower. Lifted suspension helps, but lockers and a decent all-terrain tire are more critical than lift height up here.
What time of year should I avoid this route?
Avoid January through March — the Bolivian Winter (altiplano rainy season) turns tracks into mud traps and flash flood zones. May through September is the dry window; nights will be brutal cold (well below freezing), but the roads are passable and the lagoons are at their most vivid.
Do I need a permit to drive this route, and is there a fee?
Several lagoons fall within CONAF-managed reserves — notably Los Flamencos National Reserve — and there's an entrance fee per person, typically around 5,000–10,000 CLP. Have cash in Chilean pesos; there are no card readers out here, and rangers do check at key entry points.
What's the hardest section and what actually makes it hard?
The stretch approaching Laguna Miscanti and the high passes near the Bolivian border is where most people get humbled — deep sand, corrugated track, and altitudes pushing 4,300+ meters hit your engine and your lungs simultaneously. Carry a cold-air intake or be ready for significant power loss, and take altitude sickness seriously; symptoms can turn dangerous fast at 14,000 feet.
How far is the nearest fuel stop, and how much range do I need?
Calama is your last reliable fuel before the route, and there is nothing resembling a petrol station once you head into the altiplano — plan for the full 300 km plus a buffer. Carry at minimum 40–50 liters of extra fuel in jerry cans; running dry out here means a very expensive, very slow rescue.
