The Carretera Austral, officially Ruta 7, is a iconic Chilean road stretching over 1,240 kilometers (770 miles) from Puerto Montt to Villa O'Higgins. Navigating this path through Chile's Aysén region is an adventure of a lifetime, renowned for its dramatic Patagonian scenery, remote towns, and challenging yet rewarding terrain. While getting there requires planning, the reward is unparalleled access to some of the world's most pristine wilderness. This guide will provide you with all the essential information to plan your journey, whether you prefer to fly, drive, or take a bus, ensuring you arrive ready to explore this incredible corner of the world.

Nearest Airports

Balmaceda Airport

BBA55 km (34 miles) south of Coyhaique

This is the primary airport for accessing the central and southern parts of the Carretera Austral. Located near Coyhaique, the largest city in the Aysén region, BBA offers connections from Santiago, making it a popular gateway.

El Tepual Airport (Puerto Montt)

PMC0 km (0 miles) from Puerto Montt

Situated at the northern start of the Carretera Austral, Puerto Montt is a crucial hub. Many travelers fly into PMC and begin their journey south, either by driving or taking ferries that bypass sections of the road.

Punta Arenas Airport

PUQ600 km (373 miles) south of Cochrane

While much further south, PUQ can be an option for those planning to tackle the very southern reaches of the Carretera Austral or combine it with a trip to Torres del Paine. It requires a significant drive north or further flights/buses to reach the start of the route.

By Flight

Flying is the quickest way to reach the vicinity of the Carretera Austral from central Chile. Most flights connect through Santiago (SCL) to either Balmaceda (BBA) or Puerto Montt (PMC). Balmaceda is ideal for a mid-route start, while Puerto Montt serves as the traditional northern gateway. Fares vary significantly by season, with peak summer (December-February) being the most expensive.

Flight Tips

  • Book flights well in advance, especially for the high season (December-February) to secure better prices and availability.
  • Consider flying into Puerto Montt if you plan to drive the entire route from north to south, or Balmaceda for a more central starting point.
  • Factor in potential delays due to Patagonian weather, especially during winter months.
  • Check baggage allowances carefully, particularly if you plan on bringing outdoor gear.

By Car

Driving the Carretera Austral is the quintessential Patagonian adventure, offering unparalleled flexibility to explore hidden gems and stunning viewpoints at your own pace. The route is a mix of paved and gravel sections, requiring careful driving and a reliable vehicle. The journey itself is a significant part of the experience, traversing diverse landscapes and necessitating strategic planning for fuel and accommodation.

Main Driving Routes

FromRouteDistanceDurationRoad Condition
Puerto Montt (Northern Start)Ruta 7 (Carretera Austral) & FerriesApproximately 1,240 km to Villa O'Higgins7-10 days (actual driving time without stops is around 30 hours, but many stops are essential)Mixed pavement and well-maintained gravel. Several ferry crossings (Caleta La Arena-Caleta Gonzalo, Hornopirén-Leptepu) are mandatory to continue on Ruta 7. Roads can be dusty in summer and muddy in wet conditions.
Bariloche, Argentina (via Futaleufú)RN 40 (Argentina) to RP 258/Ruta CH-231 (Chile)Approx. 200-250 km to Futaleufú (border crossing), then south on Ruta 71 day to Futaleufú, then additional days for Ruta 7RN 40 is mostly paved in this section. The border crossing roads are generally well-maintained gravel. Chilean Ruta 7 will then be mixed paved and gravel.
Punta Arenas (Southern Access)Ruta 9 (Chile) / RN 40 (Argentina)Approx. 600 km to Cochrane (entry to central Carretera Austral)Minimum 1-2 driving days (excluding ferry crossing)Ruta 9 is mostly paved heading north. RN 40 in Argentina is also largely paved. However, reaching the Carretera Austral proper from the south can involve significant gravel sections and potentially a ferry from Puerto Yungay to Río Bravo.

Driving Tips

  • A 4x4 vehicle is not strictly necessary but highly recommended for comfort and capability on gravel roads, especially if you plan to explore side roads.
  • Always carry spare fuel, especially in more remote sections where gas stations can be hundreds of kilometers apart. Check maps for fuel stops.
  • Download offline maps (e.g., Maps.me, Google Maps offline) as cell service is very limited along much of the route.
  • Be prepared for changing weather conditions, including rain, strong winds, and temperature fluctuations. Pack layers.
  • Book ferry crossings in advance, particularly during peak season, as they can fill up quickly and are essential for continuing on Ruta 7.

By Bus

Traveling by bus along the Carretera Austral is a feasible, albeit slower, option for those without a private vehicle. Bus services connect the main towns, but direct end-to-end routes are rare, often requiring multiple transfers and sometimes even ferry connections. It offers a chance to meet locals and fellow travelers, providing a more immersive, albeit less flexible, experience.

Bus Tips

  • Bus schedules can be infrequent and are often adjusted seasonally, so always confirm departure times locally.
  • Tickets are best purchased a day or two in advance, especially for popular routes during high season.
  • Be prepared for long journeys on gravel roads, which can be bumpy and dusty. Comfort levels vary between companies.
  • Some sections of the Carretera Austral, particularly the northern part, require bus passengers to take ferries with the bus or transfer to another bus on the other side.
  • Bring snacks, water, and entertainment, as stops can be limited and journeys lengthy.

Local Transport

Once you arrive in the towns along the Carretera Austral, local transport is primarily by taxis (often shared colectivos) or local buses that connect the nearest villages. In smaller, more remote areas, hitchhiking is a common and generally safe way to get around, though it requires patience. For exploring national parks and remote trailheads, a private vehicle remains by far the best and often only option.
