Atacama Desert Mining Circuit
High-altitude mining roads in Earth's driest desert
This circuit connects abandoned copper and nitrate mining operations scattered across the Atacama’s moonscape between Calama and San Pedro de Atacama. The route follows bone-dry mining roads past ghost towns like Chacabuco and Humberstone, crosses the Salar de Atacama at 7,500 feet, and climbs to active mines at 14,000+ feet elevation. Expect corrugated roads that’ll rattle your teeth loose and sudden elevation changes that’ll leave you gasping in the thin air.
Expert difficulty due to extreme altitude, zero margin for error, and complete remoteness. Serious 4WD with low range essential for steep mining roads and loose volcanic scree. Carry minimum 5 gallons extra fuel, 2 days water per person, and emergency shelter. Avoid December-February flash flood season. Permits required for some mining areas—check in Calama. What you get: otherworldly landscapes, genuine solitude, and bragging rights for conquering one of Earth’s most hostile environments.

Frequently asked questions
Can a lifted Tacoma or 4Runner handle this trail, or do I need something more serious?
A well-built Tacoma or 4Runner with low range, all-terrain tires, and a skid plate setup can manage it, but stock anything will get destroyed on the rocky mine roads. High-clearance, a locking diff (rear at minimum), and a reliable cooling system for sustained altitude climbing are non-negotiable.
Is the trail accessible year-round or does weather shut it down?
Best window is March through November. December through February brings the Bolivian winter, which pushes violent afternoon thunderstorms and flash flooding across the altiplano — at 14,100 ft, that's a serious problem on exposed mining tracks with no drainage infrastructure.
Do I need permits, and how do I get them before showing up?
Yes — sections of this circuit cross active and legacy private mining concessions in addition to CONAF-managed land. Contact CONAF's Antofagasta regional office and research which mining companies hold concessions along your specific route before you go; showing up at a mine gate without paperwork gets you turned around fast.
What's the hardest section and what should I actually expect?
The most punishing segments are the high-altitude mine access tracks above 13,000 ft — loose fractured rock, zero traction margin, and grades that combine with thin air to thermal-stress your engine hard. Altitude affects your judgment too; budget extra time, go slow, and expect 185 miles to feel like twice that.
How much fuel do I need to carry, and is there any water along the route?
Calama is your last reliable fuel stop — carry enough for 300+ km of hard, low-gear driving, which burns significantly more than highway figures; two spare jerry cans minimum. Water sources do not exist on this circuit; the Atacama is the driest desert on Earth, so carry all drinking and vehicle water from Calama.
