Carretera Austral — Puerto Montt to Villa O’Higgins via the Patagonian Fjords
The end of the road. Literally.
Ruta 7, the Carretera Austral, was hacked out of some of the most hostile terrain on the planet by Pinochet’s military engineers between 1976 and 2000. It runs from Puerto Montt in the Chilean Lake District south to Villa O’Higgins at the end of the road — literally, there is no road south from there. The route threads through old-growth temperate rainforest, alongside turquoise glacial rivers like the Río Baker and the Río Cochrane, past active volcanoes, hanging glaciers, and fjords so deep they swallow the light. Key waypoints include the ferry crossing at La Arena/Caleta Gonzalo (unavoidable), the dramatic narrows at Chaitén, Puerto Río Tranquilo for Marble Caves access, and Cochrane — the last real town before the road turns feral. The southern 200km to Villa O’Higgins is largely unpaved, rutted deep in wet season, and gorgeous in a way that makes you forgive the rocks.
A well-built, high-clearance 4WD with a full-size spare (or two) is the right tool. Stock SUVs with road tires have been dragged out of ditches here at great expense. Rain is the constant variable — Chaitén and south can see 4,000mm per year, which means river crossings change daily and dirt sections turn to clay. Fuel spacing is wide: Coyhaique is the main hub; elsewhere, carry extras and top off every chance you get. Ferries require advance booking in peak season (December–February). Budget 7–14 days minimum to do it without turning it into a highway run. This is one of those routes you do once and spend the rest of your life trying to explain.

Frequently asked questions
Can a stock Tacoma or 4Runner handle the Carretera Austral without modifications?
A stock high-clearance 4WD like a Tacoma or 4Runner can handle the route, but carry at minimum two full-size spares — the gravel chews through tires fast and tire shops are scarce south of Coyhaique. Skid plates and a quality suspension are strongly advised given 1,240km of washboard and embedded rock.
Is the Carretera Austral drivable in winter (June–August)?
Technically possible in sections, but the southern half becomes extremely hazardous — mud, ice, and several ferry crossings run reduced or suspended schedules in winter. Stick to November through March; even then, the weather in Aysén can turn violent with zero warning.
Do you need permits or pay fees to drive the Carretera Austral?
No permit is required to drive the road itself, but two mandatory ferry crossings — at Hornopirén and Caleta Tortel/Puerto Yungay — cost money and require advance reservations in peak season, especially if you're hauling a large rig. Budget for multiple ferry crossings and book the Hornopirén–Caleta Gonzalo leg as early as possible.
What's the hardest section of the route and what makes it brutal?
The stretch south of Cochrane toward Villa O'Higgins is the roughest — narrower, looser gravel, more washboard, and the ferry crossing at Puerto Yungay is the final choke point before the literal end of the road. Distances between fuel and services stretch to 150–200km, so if something breaks down here, you're on your own for a while.
How far can you realistically drive between fuel stops, and is there a critical gap to plan for?
The worst gap is roughly 220km between Cochrane and Villa O'Higgins — carry extra fuel or you will not make it back out. Coyhaique is the last major city with reliable fuel and parts; stock up there before pushing south.
