The Carretera Austral is Chile's Route 7 (CH-7), and it runs about 1,240 km (770 miles) south from Puerto Montt to Villa O'Higgins through the fjords, forests and ice fields of northern Chilean Patagonia. Three ferry crossings are part of the road itself, not detours around it, and the southern half is still largely gravel. That combination — mandatory boats, unpaved surface, very long gaps between anything resembling a town — is what makes it a genuine expedition rather than a scenic drive. This guide covers the ferries, the paving picture, where the fuel actually is, and what the southern-hemisphere season means for planning.
The ride in one paragraph
Route 7 exists because Chile's southern territory is almost impossible to reach overland. Thick forest, fjords, glaciers and steep mountains meant that for decades traffic between central Chile and its Patagonian provinces had to detour through Argentina. Construction began in 1976 under the Chilean Army's engineering command, with more than 10,000 soldiers involved; the road opened to traffic in 1988, reached Puerto Yungay by 1996, and the final 100 km (62 miles) to Villa O'Higgins only opened in 2000. A branch to Caleta Tortel was finished in 2003. Despite its length, it provides road access to roughly 100,000 people. The largest place on the whole route is Coyhaique, whose population was 53,715 at the 2010 count. Everything about riding it follows from those numbers.

The three ferries, and why they set your itinerary
Riding the full route means taking three boats. The first is a 40 to 45 minute crossing between Caleta La Arena and Caleta Puelche, roughly 45 km (28 miles) south of Puerto Montt. It runs around the clock with departures roughly every half hour during the day, and in the December to February peak the frequency increases further. You cannot book it; it is first come, first served, so expect a queue in high season.
The second is the serious one. From Hornopirén, about 110 km (68 miles) south of Puerto Montt, a crossing takes you to Leptepu, then a short road link, then a second boat from Fiordo Largo to Caleta Gonzalo — roughly five hours of boat time in total. Tickets must be bought in advance, sailings are limited, and in January and February vehicle bookings are typically made weeks ahead. Riders who turn up hoping for a space in peak season are the ones who end up riding round through Argentina.
The third, from Puerto Yungay to Río Bravo, takes about 50 minutes and opens the final 100 km (62 miles) to Villa O'Higgins. It is a short, frequent, undramatic crossing by comparison, but it is still a fixed timetable in a place with no alternative road.
The practical consequence is that your daily distances are set by boat schedules rather than by how far you feel like riding. Build the ferries into the plan first and fill the riding around them.
Pavement, ripio and roadworks
The road began almost entirely unpaved and has been asphalted in stages ever since, which means any description of the surface has a shelf life. As of the 2026 edition of the Worldly Adventurer Carretera Austral guide, around 90 per cent of the stretch from Puerto Montt to Puyuhuapi is paved. South of Puyuhuapi you are into gravel and continuing construction projects, with roadworks concentrated on the sections directly south of Puyuhuapi, Coyhaique and Villa Cerro Castillo. Those works can add up to an hour to a day's travel, and closures cluster in the early afternoon.
Ripio on this road is not the graded, predictable gravel of a forest track. Expect washboard, loose stones on the racing line, soft edges where the grader has thrown material, and long straights where speed creeps up until the front end starts moving. The standing advice for cars is to stay under 60 km/h (37 mph); on two wheels that is a sensible ceiling too. Punctures are the most common failure and stone chips are the second.
Live road-state information for the region is published in Spanish through the regional roads portal at lavia.cl, and the tourist information offices in Puerto Montt and Coyhaique know which sections are shut for works that week. Verified in August 2026, that is still the most reliable way to find out before you commit to a day's route.
Fuel, and the real spacing between stations
This is the number that catches people out. Fuel exists at Hornopirén, Chaitén, Futaleufú, La Junta, Puyuhuapi, Puerto Cisnes, Mañihuales, Puerto Aysén, Puerto Chacabuco, Coyhaique, Villa Cerro Castillo, Puerto Río Tranquilo, Chile Chico, Cochrane and Villa O'Higgins. That looks like a lot until you map it against 1,240 km of road with almost nobody living beside it — and note that Puyuhuapi has been reported as diesel only, which matters if you were counting on it.
Two habits solve the problem. Fill up every single time you pass a station, whatever the gauge says. And carry enough spare fuel to cover the longest gap on your planned day plus a reserve, because a station in a village of a few hundred people can be out of stock, shut for lunch, or shut because the delivery truck is stuck behind roadworks. Fuel quality on the Chilean side is generally consistent, but the southern stations are small operations with low turnover, so a fuel filter that is easy to reach is worth having.
Mobile coverage follows the same pattern as fuel: it exists in the towns and disappears between them. Entel has the widest coverage along the route, with Claro second, but neither is a reason to plan on being reachable.
Season, weather and border paperwork
Season. Unlike an Alpine pass, the Carretera Austral has no single official opening date — it is a working road for the communities along it. What changes with the seasons is everything that makes it rideable: ferry frequency, daylight, roadworks progress and the state of the gravel. The practical window is the southern summer, roughly November through March, with December to February the busiest and the ferries at their highest frequency. Outside that, daylight shrinks fast at these latitudes and boat schedules thin out. Check ferry operator sites and regional road status before you commit, because both change year to year.
Weather. This is temperate rainforest for much of its length. Rain is not a seasonal event, it is the climate, and the wind that Patagonia is famous for arrives as you move south into the open country around Coyhaique and beyond. Wet ripio is considerably less forgiving than dry ripio, and the gravel dust that coats everything on a dry day turns into a paste that finds bearings and chain links.
Border paperwork. Many riders combine Route 7 with sections of Argentine Patagonia, and the main crossing on the northern half is Paso Futaleufú, 10 km east of the town of Futaleufú, linking to Esquel. If you are riding a hired bike, get written authorisation from the rental company to take it out of Chile before you leave — this is the single most common reason riders get turned back at a South American border. For your own machine you will need the vehicle title or registration in your name, the temporary import permit issued when you entered, your passport, licence and an International Driving Permit, plus separate insurance valid in the country you are entering. Chilean and Argentine border posts on this route are small and their opening hours are not 24/7, so treat them as another fixed timetable alongside the ferries.
Gear notes for the Carretera Austral
Everything that makes this road special also makes it hostile to a phone-and-signal approach to navigation. Coverage is town-only, the junctions that matter are unsigned, and a wrong turn can cost you a ferry slot. Having the whole region stored in advance for offline route planning is not optional here, and a purpose-built motorcycle riding system handles the constant drizzle far better than a handset on a bar mount. Steep-sided fjord valleys are exactly the terrain where a single-constellation fix wanders, which is why our explainer on multi-constellation positioning is relevant rather than academic. On gravel this long, tyre pressure is a live variable, not a pre-trip checkbox: many riders drop pressure for ripio and forget to put it back before a paved stretch. Our tyre pressure guide covers the trade-offs and a TPMS sensor tells you about a slow puncture while you can still reach the next village. Camping between towns is normal on this route, so a bi-directional fast charger keeps the intercom and cameras alive on day five. If you are continuing east, our Ruta 40 guide covers the Argentine counterpart, and the best motorcycle roads in South America page puts the whole continent in order.
FAQ
How long does the Carretera Austral take on a motorcycle?
Two weeks covers most of it comfortably and three weeks is better, because the ferries, roadworks and weather all eat time you did not budget. Riders who try to do the full 1,240 km in under a week generally end up skipping the southern gravel entirely.
Do you need a big adventure bike?
No, but you need something you are happy to ride on loose gravel for days at a time, with luggage. Ground clearance and a manageable weight matter more than engine size. Whatever you ride, make sure it has a usable spare tube or repair kit and that you can actually change a tyre at the roadside.
Are the ferries included, and can you book them?
They are separate from the road and paid for individually. The Caleta La Arena crossing cannot be booked and works first come, first served. The Hornopirén to Caleta Gonzalo sailings must be booked ahead, and vehicle spaces in January and February typically need to be reserved weeks in advance. Check the operators' own sites for current schedules and fares.
When is the best time to ride it?
The southern summer, roughly November to March. December to February brings the most ferry departures and the longest daylight, along with the most traffic and the hardest ferry bookings. Shoulder months are quieter but the timetables thin out.
Can you ride it and cross into Argentina?
Yes, and many riders do — Paso Futaleufú is the main crossing on the northern half, connecting to Esquel. You need your own vehicle paperwork or written permission from the rental company, an International Driving Permit alongside your home licence, and insurance valid in the country you are entering. Border posts here keep limited hours.
