Ruta de los Seismiles Catamarca
Six-thousand meter peak circuit extreme challenge
This brutal 320-kilometer circuit links Argentina’s highest accessible peaks through mining roads that climb above 4,800 meters between Fiambalá and Tinogasta. You’ll navigate loose volcanic scree on the approach to Ojos del Salado base camp, cross the Salar de Antofalla’s crystalline expanse, and follow abandoned sulfur mining tracks toward Cerro Pissis. The route demands precise navigation through unmarked intersections where one wrong turn adds 100 kilometers through roadless puna.
Expert-only territory requiring serious altitude preparation, emergency gear, and a properly equipped expedition vehicle with spare everything. Attempt only during dry months (April-November) when sudden storms won’t trap you above 5,000 meters. Fuel availability is critical — carry enough for 500 kilometers and coordinate cache points in advance. This isn’t a trail; it’s a high-altitude survival test that rewards the prepared with access to some of the planet’s highest driveable terrain and complete solitude among six-thousand-meter peaks.

Frequently asked questions
Can a stock Land Cruiser or lifted 4Runner handle this route?
No. This trail demands a purpose-built expedition vehicle — think long-range fuel capacity (400+ km range minimum), reinforced suspension, all-terrain tires rated for sand and sharp volcanic rock, and a recovery kit. A stock rig will leave you stranded at altitude with no one coming to help.
When is the trail actually passable and what closes it?
April through November is the window. December through March is Andean summer storm season — flash floods and road washouts are common and can trap you for days. Snow and ice at 15,000+ ft can shut sections down outside that window too.
Do I need a permit and where do I get it?
Yes, a permit is required through the Catamarca Provincial Government. Sort this out in Fiambalá or at the provincial offices in San Fernando del Valle de Catamarca before you leave — attempting to wing it at the trailhead in this region is not a viable plan.
What's the hardest section and what actually makes it dangerous?
The sustained high altitude is the real enemy — you're operating above 14,000 ft for extended stretches with peaks hitting 15,748 ft. Combined with soft sand, loose volcanic rock, and zero rescue infrastructure, a mechanical failure or medical emergency (altitude sickness hits hard and fast up here) becomes a life-threatening situation fast.
How much fuel do I need to carry and where's the last reliable fill-up?
Fiambalá is your last confirmed fuel stop before the route — carry enough for at least 400 km of hard running in low range, which burns significantly more than highway driving. There are no fuel sources on the route itself, and at altitude your engine is already fighting, so plan conservatively.
