Sierras de Famatina La Mejicana Gold Rush Circuit
Historic gold mining circuit through Argentina's highest peaks.
La Mejicana was Argentina’s richest gold mine, and this circuit follows the original supply road to 4,200 meters through the Sierras de Famatina. The route starts at Chilecito and climbs past the abandoned Estación 8 cable car terminal, where rusted machinery still clings to the mountainside. Technical switchbacks on loose shale lead to the mine ruins at La Mejicana, with stunning views across the Salinas Grandes and distant Aconcagua on clear days.
Moderate to difficult depending on conditions—stock high-clearance handles most sections, but loose rock and steep grades favor 4WD low range. The final push to the mine requires careful tire placement on deteriorated road surface. Best from April to October when snow doesn’t block the upper reaches. Carry extra water and warm clothing—afternoon storms roll in fast. This route delivers legitimate mining history in Argentina’s most overlooked mountain range, plus some of the country’s best high-altitude scenery.

Frequently asked questions
Can a stock Hilux or Patrol handle this trail without a lift?
A stock high-clearance 4WD will get you through, but the rocky gravel sections and washouts above 4,000m reward extra clearance. A lifted rig is more comfortable, not strictly required — but don't attempt it in a 2WD or low-clearance SUV.
Is the trail accessible in winter?
Best season is April through October. From November to March, afternoon storms, snow at altitude, and flash flooding on the lower sections can close the route without warning — the road to La Mejicana becomes genuinely dangerous when wet.
Do I need a permit to drive the circuit?
No permit is currently required to drive the trail. The route passes through land managed by the Gobierno de La Rioja — check locally in Chilecito for any seasonal closures or access restrictions before you head up.
What's the hardest section and what makes it gnarly?
The push above 3,500m toward La Mejicana mine is where it gets serious — loose gravel, tight switchbacks, and significant exposure on the edge. Altitude fatigue hits hard here; take it slow, your engine will be gasping too.
How far is the nearest fuel stop and should I carry extra?
Chilecito is your last reliable fuel before the circuit — fill up completely. The loop is 107km of remote high-altitude driving with no services, so carry a minimum 20-litre jerry can. Cell service is spotty at best, so don't count on calling for help if you run dry.
