Circuito Grande Tierra del Fuego
World's southernmost island circumnavigation
This massive 900-kilometer circuit takes you around the entirety of Isla Grande de Tierra del Fuego, from Ushuaia’s tourist crowds through the Chilean section via rutted logging roads that turn to axle-deep mud soup, then back into Argentina past windswept sheep estancias and abandoned mining camps where you’ll cross the same rivers that broke early explorers. The route includes the infamous Paso Garibaldi through untouched lenga forests and technical creek crossings near Estancia Harberton that can strand you for days.
This difficult route demands experienced expedition skills — river crossings change hourly with tides, weather shifts from sun to sideways sleet in minutes, and help is 200 kilometers away on the best sections. Full expedition kit essential: recovery gear, spare parts, camping gear rated for Patagonian wind. April through November only when rivers aren’t flash-flooding. Border crossings with Chile add paperwork delays, but you’ll complete one of the world’s most remote island circumnavigations and understand why Magellan called this the Land of Fire.

Frequently asked questions
What's the minimum vehicle setup to attempt this route?
A stock SUV won't cut it here. You need a fully expedition-equipped 4WD with a lift, all-terrain tires, recovery gear, dual spare tires, and enough fuel range for 300–400km between reliable fill-up points. Mud-specific tires are strongly advised — the boggy sections on the Chilean side will swallow underprepared rigs.
What's the best time of year to run this circuit?
November through March is the Patagonian summer and the most favorable window — longer daylight, less mud, and border crossings are more reliably operational. April and October are shoulder months that can work but expect more rain, heavier mud, and shorter days. Winter conditions from May through August make significant portions impassable or outright dangerous.
Do you need permits or special documentation to cross into Chile on this loop?
Yes — the circuit crosses between Argentina and Chile multiple times, so you need your vehicle's title, proof of insurance valid in both countries, and your passport. Temporary vehicle import permits (TIP) are required at each Chilean border crossing. Check current crossing hours in advance; some remote crossings have limited operating schedules and don't run 24/7.
What's the hardest section of the route and what makes it technical?
The deep interior tracks on the Chilean side of the island — particularly around Lago Fagnano and the sections accessing remote estancias — are the crux. Deep wheel-rut mud, water crossings with no established depth markers, and zero recovery support make these segments serious. If it's been raining for several days, some of these tracks become genuinely impassable and there's no one coming to help you.
How much fuel do you need to carry, and where can you actually refuel?
Ushuaia is your main resupply point at the start and end of the loop. On the Chilean side, fuel availability is extremely limited and unreliable — carry enough range for at least 400km as a conservative buffer. A long-range auxiliary tank or multiple jerry cans is not optional on this route, it's mandatory.
