Ruta del Cobre Sewell Mining Ghost Town Circuit
Copper ghost town carved into the Andes.
Sewell sits frozen in time at 2,130 meters — a complete mining town built into the Andean mountainside where 15,000 people once lived extracting copper for the world. The approach road switchbacks up from Rancagua through desert foothills, passing massive tailings and industrial ruins before reaching the ‘City of Stairs’ itself. UNESCO protects the site now, but the mining roads continue higher to active Teniente operations and spectacular overlooks of the central Andes.
Moderate route suitable for most high-clearance vehicles, though the altitude and switchbacks demand attention. Regular passenger cars can reach the lower viewpoints, but the full circuit requires 4WD. Open year-round but winter brings snow and ice. Tours available through CODELCO, but the real adventure lies in the network of mining access roads that spider higher into the mountains. You’ll witness Chile’s copper legacy carved directly into the continental spine — brutal, beautiful, and absolutely essential to understanding this country.

Frequently asked questions
Can a stock SUV handle this trail, or do I need a lifted rig?
A stock high-clearance SUV like a 4Runner, Hilux, or Pajero is sufficient. The gravel switchbacks are the main challenge, not rock crawling — but low ground clearance sedans will scrape and struggle on the rougher sections.
When is this trail actually driveable, and what happens if I go in winter?
October through April is the window. Winter brings snow and ice at elevation that can close the upper sections completely — this tops out near 7,000 ft and the Andes don't mess around from May to September.
Do I actually need a permit to drive this, and how do I get one?
Yes — Sewell is a UNESCO World Heritage Site managed by CODELCO, Chile's state copper company, and access requires prior authorization through their official channels at codelco.com. Show up without clearance and you're turning around at the gate.
What's the hardest part of this circuit and what should I actually expect?
The switchback climb into the Sewell townsite is the crux — tight turns on loose gravel with significant exposure. It's not technically extreme, but the combination of altitude, narrow road width, and sheer drop-offs demands focused driving and no passenger-seat distractions.
Is there anywhere to get gas or food along the route, or do I need to fuel up in Rancagua?
Fuel up in Rancagua before you leave — there are no services on this circuit. It's a 45-mile route and you'll want buffer range for backtracking or detours, so leave town with a full tank.
