Carretera Austral 2026: a 10 day drive through Patagonia

Route 7 runs about 1,240 km through Chilean Patagonia, from Puerto Montt to Villa O'Higgins, through temperate rainforest, fjords and glacial valleys. It was built from 1976 onwards to connect communities that had no land route to the rest of Chile, and much of it is still gravel.

This is the most demanding route in this series by a wide margin, and the most rewarding. It is also the one where planning failures have real consequences, because the gaps between settlements are long and the ferries are not optional.

How long it takes

Seven days gets you from Puerto Varas to Coyhaique or a little beyond, seeing the northern highlights.

Ten to twelve days reaches Puerto Río Tranquilo and Cochrane, which includes the Marble Caves and the best of the southern section. This is the version most people should plan.

Three weeks gets you to Villa O'Higgins at the end of the road, which is genuinely the end: beyond it there is no road, only a boat and a hiking crossing into Argentina.

Do not plan this route to a tight schedule. Weather closes roads, ferries run late, and the buffer day you build in is the one that saves the trip.

When to go

December to February is southern summer and the main season. Long daylight, all services open, ferries at full timetable. It is also when the ferries fill.

November and March are shoulder. Quieter, still workable, some services reduced. March brings autumn colour in the southern beech forests.

April to October is winter. Short days, heavy rain in the north, snow further south, many businesses closed and ferries reduced. Not recommended for a first visit.

The ferries

This is the part to get right before anything else.

The road is interrupted by water in the north and the crossings are part of the route, not alternatives to it. The critical one is Hornopirén to Caleta Gonzalo, a four to five hour sailing that runs only in high season and sells out weeks or months ahead in January and February.

Book it as soon as your dates are fixed, before accommodation. Everything else on the northern section arranges itself around when you can get on that boat.

There is a longer alternative via Argentina if you cannot get a sailing, which adds days and two border crossings.

The route, north to south

Puerto Varas to Hornopirén, around 110 km. Start point for most people. Puerto Varas is a comfortable town on a lake with volcanoes behind it, and the last place with a full range of shops.

Caleta Gonzalo to Chaitén, around 60 km. After the ferry. Pumalín Park, donated by the Tompkins conservation project, with short trails through temperate rainforest.

Chaitén to Futaleufú, around 150 km. An optional detour east to one of the world's better whitewater rivers. Worth two days if rafting appeals.

Chaitén to Puyuhuapi, around 200 km. Long gravel stretches. Puyuhuapi is a small village founded by German settlers, with hot springs nearby.

Queulat National Park. The hanging glacier, a valley glacier that ends on a cliff and drains over it in waterfalls. A two-hour round-trip walk from the road to the viewpoint.

Puyuhuapi to Coyhaique, around 225 km. The regional capital and the biggest town on the route: banks, supermarkets, mechanics, fuel. Restock here.

Coyhaique to Puerto Río Tranquilo, around 220 km. Past Cerro Castillo, whose jagged peaks are among the best mountain scenery in the region. Puerto Río Tranquilo is the base for the Marble Caves, reached by small boat across Lake General Carrera.

Puerto Río Tranquilo to Cochrane, around 115 km. Along the lake, past the confluence where the Baker and Neff rivers meet. Cochrane is the last town of any size.

The vehicle

A high-clearance vehicle is a real recommendation here, not a preference. Long sections are gravel, and after rain they develop ruts and washboard that punish a low car.

Four-wheel drive is useful rather than essential if you stay on Route 7 itself, and becomes more valuable on the side roads and in poor weather.

Two practical points that catch people out. Check whether your rental allows travel on the full length of the Carretera and permits border crossings if you plan to enter Argentina, as many contracts restrict both. And carry a spare tyre you know how to fit, because punctures on gravel are common and help can be hours away.

Fuel, food and connectivity

Fuel stations exist in the towns and almost nowhere between them. Fill at every opportunity in the southern half. Carry a jerry can if you plan to reach Villa O'Higgins.

Supermarkets are limited outside Coyhaique. Buy several days of food when you can.

Mobile coverage is patchy to absent for long stretches. Tell someone your route, download offline maps, and do not rely on being able to call for help.

Common questions

Can I do this by bus?

There are buses along parts of the route, but they are infrequent, and the timetable rather than your interest decides where you stop.

North to south or south to north?

North to south as described is the usual direction and matches the ferry timetables better. Flying into Balmaceda near Coyhaique and driving out in both directions is a good option for a shorter trip.

How far ahead do I need to book the ferries?

Months, for the vehicle crossings in high season. The ferries are the fixed points of this route: fix them first and build the driving days around them, not the reverse.

Do I need a 4x4 for the Carretera Austral?

Not strictly, as much of Route 7 is now paved, but high clearance genuinely helps on the remaining gravel. Confirm the rental allows the route and check the spare tyre before leaving.

Is it safe?

Chile is a stable country and the risk here is environmental rather than criminal: weather, remoteness and road conditions.

Can I cross into Argentina with a rental car?

Only with the right paperwork. Chilean rental companies need advance notice to issue a border permit, and it carries a fee. Arriving at the crossing without it means being turned back.

Do I need Spanish?

Some. English is limited outside tourist businesses, and in the smaller villages it is rare.

Planning your version

Fix the ferry first, then build the days around it. Give the planner your dates and driving limit, then sanity-check each leg against fuel and accommodation, which are the two constraints that decide where a day can end on this route.
