Carretera Austral by Car: Full Route With Ferries and Without

Carretera Austral by car: a full route with ferries and how to do it without them

The Carretera Austral is one of the most beautiful roads in the world. It's not an exaggeration, it's the consensus of anyone who has driven its 1,240 kilometers of Valdivian forest, fjords, volcanoes, turquoise rivers and villages lost in Chilean Patagonia. Ruta 7, as it's officially called, links Puerto Montt to Villa O'Higgins crossing Aysén, the most isolated and least inhabited region of Chile. To get from the start to the end by car, you'll need ferries. That's the route's particularity: the road isn't continuous, and in two stretches the only way through is by sea or fjord.

But there's a second version of the Carretera, equally beautiful, without ferries, and accessible for whoever has less time or doesn't want to depend on boat schedules. This article covers both.

In short: the complete Carretera Austral goes from Puerto Montt to Villa O'Higgins and requires two mandatory ferries (La Arena→Puelche and Hornopirén→Caleta Gonzalo). The ferry-free version enters through Argentina via Paso Futaleufú or Paso Huemules and covers the most beautiful part of the route to Cochrane or Coyhaique. Both versions have severe ripio, an SUV is the minimum recommended, spare tires are mandatory. Best time: November to March.

The complete route, from Puerto Montt to Villa O'Higgins

The Carretera officially begins in Puerto Montt, but in the very first kilometers you hit the first interruption: the sea channel between La Arena and Puelche. The ferry here is short (20-30 minutes), frequent and low-cost, it doesn't usually create a waiting problem outside the full summer.

The next stretch advances along the coast of Lago Chapo to Hornopirén, where the second and most important ferry of the route is: the crossing to Caleta Gonzalo, inside Parque Pumalín. This ferry lasts approximately 4 hours, passes through fjords of absurd beauty and is the heart of the experience for whoever does the complete route. The frequency is lower, usually 1 to 2 departures a day in summer, none on bad-weather days. Reserve in advance with Naviera Austral, especially in December and January.

From Caleta Gonzalo, the real Carretera begins: dense forest, a gravel road, small villages. The landmarks of the northern stretch to Coyhaique:

Chaitén, the first sizable city after Caleta Gonzalo, rebuilt after the eruption of the Chaitén volcano in 2008. Worth stopping to refuel and learn the history of the place.

Futaleufú, a mandatory 75 km detour. One of the best rivers for rafting in the world, a charming village, and Lago Espolón with greenish water that looks unreal. Even whoever doesn't raft will want to stop here for two days.

Puyuhuapi, a German hamlet founded by settlers in the 20th century, with the famous Termas del Ventisquero accessible only by boat (they leave from Puyuhuapi). Queulat National Park is a few kilometers away, the hanging Ventisquero Colgante glacier is one of the most impressive views of the entire route.

Coyhaique, the capital of Aysén and the biggest city on the Carretera. A complete refueling point (mechanic, supermarket, hospital, fuel). Many people use it as a base to explore the region or rest before continuing.

Cochrane, the last city with reasonable infrastructure before the final stretch. Parque Patagonia is in this region, one of the best-preserved and most beautiful parks in Chile, with abundant fauna (pumas, guanacos, huemuls) and trails of various levels.

Caleta Tortel, a stilt-house village with no streets, only wooden walkways over the coast. A 22 km detour off the main route, but worth every meter. One of the most picturesque communities in Patagonia.

Villa O'Higgins, the end of the road. To get there, there's one more optional ferry stretch across Lago O'Higgins. From here, the only overland advance is on foot or by boat to Argentina via the Los Antiguos border.

The ferry-free version, entering through Argentina

Whoever doesn't want to depend on boat schedules has an alternative that delivers most of the route's beauty. The idea: enter Chile through Argentina and pick up the Carretera already in the middle, skipping the northern stretch that requires the two ferries.

Via Paso Futaleufú: crossing from Esquel or Trevelin on the Argentine side, you arrive straight at the village of Futaleufú, already on the Carretera. From there, the route continues south, Puyuhuapi, Coyhaique, Cochrane, Caleta Tortel, all accessible without any ferry. This pass is the most recommended for this version.

Via Paso Huemules: leaving from Coihaique Alto on the Argentine side, you arrive directly at Coyhaique. Less transition scenery, but useful for whoever is going to do only the southern stretch.

What you lose without the ferries: Parque Pumalín and the stretch between Caleta Gonzalo and Chaitén, which is dense vegetation and a fjord landscape different from everything else on the route. It's a real loss, but the rest of the Carretera, from Futaleufú south, already justifies any trip.

Vehicle, road and what to prepare

Vehicle type: a high SUV is the minimum recommended. A passenger car passes on a good part of the route, but some severe ripio stretches, especially near Villa O'Higgins and on the stretch from Caleta Gonzalo south, demand clearance and firmer traction. A 4x4 extends the comfort and safety.

Tires: take at least two spares. A puncture on ripio on the Carretera isn't a rarity, it's a statistical certainty on a long trip. A tire shop exists in Coyhaique; on the rest of the route, improvise.

Fuel: refuel whenever possible. Some stretches have distant stations with unpredictable hours. In Coyhaique fill the tank and any extra reservoir you have.

Connectivity: sporadic phone signal between villages. Download offline maps before entering any remote stretch. Starlink Roam is the only way to have continuous internet on deserted stretches.

Documentation: the same standard Chilean documentation, IDP, Green Card, the vehicle registration, an owner's authorization if applicable. Plus the SAG control at the border (no fresh food, meat or non-industrialized dairy, a sniffer dog present).

Best time and how long to take

Season: November to March is the ideal window, long days (up to 18h of light in the austral summer), drier roads, ferries with more frequency. Outside of that, snow closes some stretches in winter and intense rain in autumn turns the heavy ripio into mud.

Duration:

Ferry-free version (Futaleufú to Cochrane): 7 to 10 days at an easy pace.

Complete route (Puerto Montt to Villa O'Higgins): 14 to 18 days to enjoy without rushing.

Complete route with long detours (Futaleufú, Parque Patagonia, Caleta Tortel): 21 days or more.

The temptation to speed up is great, the road looks short on the map. In practice, severe ripio, compulsory photo stops and attractions that appear without warning turn 200 km into a whole day.

FAQ

Do you need to reserve the ferries in advance?

The La Arena→Puelche ferry doesn't need a reservation, it's frequent. The Hornopirén→Caleta Gonzalo one (Naviera Austral) does, especially in December and January. Reserve on the Naviera Austral site at least 2 to 4 weeks in advance in summer.

How much does the complete route cost in fuel?

Gasoline in Chile is more expensive than in Brazil. On the Carretera, the price per liter rises in remote villages. The total fuel cost depends on the vehicle's consumption, on average, an SUV consuming 10km/L on the complete route represents a significant budget.

Does a passenger car handle it?

Most of the route, yes, with careful driving. The Hornopirén to Coyhaique stretch is viable. The Cochrane to Villa O'Higgins stretch already demands more of the vehicle. The decisive factor: minimum clearance (at least 18 cm). Without it, the ripio gets the underbody first.

Can you do the complete route alone?

Yes, but it demands more attention to fuel planning, ferries and basic emergency mechanics. Groups of two cars are the safest setup for remote stretches.

And if you need a mechanic in the middle of the route?

Coyhaique has complete shops. In the other villages, mechanics are basic, tire repair, small fixes. A serious problem on a remote stretch = a tow or waiting for someone to pass. Prevention here is worth much more than a cure.

To wrap up

The Carretera Austral is the kind of road that changes the yardstick of what you consider a "good trip". With ferries or without them, with 10 days or 21, you'll finish the stretch with the feeling that Chilean Patagonia delivered more scenery per kilometer than anywhere else you've ever been. And you'll want to come back to see what there wasn't time to stop for.
