Camino a Laguna Brava – San Juan High Andes
Extreme altitude access to pristine wilderness
The Camino a Laguna Brava pushes into the most remote corner of San Juan Province, where the road degrades to wheel tracks threading between 20,000-foot volcanic peaks toward the Chilean border. Starting from the mining town of Iglesia, the route climbs relentlessly through the Cordillera de Ansilta before dropping into the Laguna Brava basin at 14,100 feet—one of Argentina’s highest accessible bodies of water. Vicuñas and flamingos inhabit this harsh landscape where oxygen sits at 60% of sea level.
This extreme route demands a well-prepared expedition vehicle with auxiliary fuel tanks, as the nearest gas is 200+ miles away. High-clearance 4WD with good tires handles the rocky terrain, but altitude sickness is the real enemy here. March through May offers the most stable weather. Laguna Brava Natural Reserve requires advance permission from San Juan’s environmental ministry. The reward is accessing one of South America’s most pristine high-altitude ecosystems, where condors soar at eye level and the silence is absolute.

Frequently asked questions
What's the minimum rig to attempt Camino a Laguna Brava?
A full expedition-spec 4WD — locking diffs, high clearance, and a minimum 40-50L auxiliary fuel capacity are non-negotiable. A stock SUV will not make it; this route punishes underprepared vehicles with soft sand, loose volcanic rock, and sustained climbs above 14,000 ft.
When is this route actually passable?
March through May is the reliable window — austral autumn brings stable conditions before winter snowfall closes the high passes. Summer (December-February) can see flash flooding on the crossings, and winter access is essentially impossible without specialized mountain equipment.
Do I need a permit to drive into Laguna Brava reserve?
Yes — Laguna Brava is managed by Argentina's Administración de Parques Nacionales and entry requires a permit. Sort this out in advance through the San Juan provincial park office or APN directly; rangers do patrol the reserve and enforcement is real.
What's the hardest section and what should I expect?
The approach climbs into sustained elevation above 13,000 ft across loose volcanic scree and deep sand crossings — your engine loses significant power up here and traction is unpredictable. There are no bailout points once you're deep in, so if a vehicle goes down mechanically, self-recovery capability and a second rig are serious considerations, not suggestions.
How far is the nearest fuel stop and is there any water on route?
Iglesia is your last confirmed fuel stop before departing — plan for the full 124-mile route plus a safety margin, which is why auxiliary fuel is mandatory. There are water crossings on route but water quality and crossing depth vary seasonally, so carry your own treated supply and never count on crossings being passable until you're standing in front of them.
