Getting to Lago General Carrera / Buenos Aires, the second-largest lake in South America, is an adventure in itself, traversing some of Patagonia's most iconic landscapes. Whether you choose to fly into a regional airport and drive, embark on an epic road trip along the Carretera Austral or Ruta 40, or take a scenic bus journey, planning is key. This guide details all the essential transportation options, helping you navigate your way to this magnificent border lake, renowned for its turquoise waters and the geological marvels of the Capillas de Mármol.
Nearest Airports
Balmaceda Airport
The primary gateway to the Chilean Aysén region. Located near Coyhaique, it's the closest major airport with regular flights from Santiago. From here, you'll need to rent a car or take a bus to reach the lake's shores.
Esquel Airport
Located in Argentina, this airport serves as a potential entry point for travelers approaching the Argentinian side (Lago Buenos Aires). Requires a significant overland journey to reach the lake, often involving border crossings.
By Flight
Flying is the quickest way to cover the vast distances to Patagonia. The most practical airport for accessing Lago General Carrera (Chilean side) is Balmaceda (BBA). From there, a car rental is highly recommended for the scenic drive to the lake.
Airlines
Flight Tips
- Book flights well in advance, especially during the peak season (December to March), as prices can increase significantly.
- Consider connecting flights via Santiago (SCL) as direct flights to Balmaceda are primarily from the capital.
- Factor in travel time from Balmaceda Airport to your specific destination around the lake; it's a 3-4 hour drive to Puerto Río Tranquilo or Chile Chico.
By Car
Driving is, without a doubt, the best way to experience the breathtaking beauty and remote corners of Lago General Carrera and its surroundings. It offers unparalleled flexibility to explore hidden gems, stop at scenic viewpoints, and truly immerse yourself in the Patagonian landscape. The Carretera Austral (Ruta 7) is an iconic route leading to the Chilean side, while Ruta 40 provides access from Argentina.
Main Driving Routes
| From | Route | Distance | Duration | Road Condition |
|---|---|---|---|---|
| Coyhaique / Balmaceda Airport (BBA) | Carretera Austral (Ruta 7 South) | Approx. 200 km to Puerto Río Tranquilo | 3-4 hours | Mostly gravel sections with some paved parts. Conditions can vary greatly with weather; expect dust in dry periods and mud after rain. Some sections are winding and narrow. |
| Puerto Montt | Carretera Austral (Ruta 7 South) | Approx. 750 km to Puerto Río Tranquilo (including ferries) | 2-3 days (multi-day journey) | A mix of paved and gravel roads, with mandatory ferry crossings. Road conditions vary but are generally passable for 2WD vehicles, though 4x4 offers more comfort and capability. |
| Los Antiguos (Argentina) | Chilean border crossing to Chile Chico (Chile) | Approximately 5 km (from Los Antiguos to Chile Chico border) | 15 minutes + border procedures | Paved roads on the Argentinian side leading to the border, then paved into Chile Chico. The road along the lake towards Puerto Río Tranquilo (Ruta 265 and Ruta 7) is mostly gravel. |
| El Calafate (Argentina) | Ruta 40 North to Perito Moreno, then Ruta 43 West to Los Antiguos | Approx. 550 km to Los Antiguos | 7-9 hours | Primarily well-maintained paved roads (Ruta 40, Ruta 43) in Argentina. Can experience strong crosswinds. From Los Antiguos, a border crossing leads to the Chilean side. |
Driving Tips
- A 4x4 vehicle is not strictly necessary but provides more comfort and confidence on the gravel sections of the Carretera Austral and allows access to more remote areas.
- Always check local road conditions before departing, especially during shoulder seasons or winter, as heavy rain or snow can cause closures or delays.
- Ensure your vehicle is in good condition, carry a spare tire (or two!), and keep your fuel tank full, as gas stations can be scarce in rural areas.
- Download offline maps, as cell signal can be intermittent or nonexistent along parts of the routes.
By Bus
Bus travel to Lago General Carrera is a viable option for those on a budget or who prefer not to drive. However, it requires more planning due to less frequent services and longer travel times compared to driving your own vehicle. Buses typically connect major towns like Coyhaique to settlements around the lake.
Bus Companies
Bus Tips
- Bus schedules are often limited, especially outside of peak season, so check times well in advance and book your tickets to secure your spot.
- Be prepared for long journeys on gravel roads, which can be dusty and bumpy. Comfortable clothing and snacks are recommended.
- From Balmaceda Airport, you'll need to take a transfer or local bus into Coyhaique before connecting to a bus heading towards Lago General Carrera.
- For cross-border travel from Argentina, buses usually go as far as Los Antiguos, requiring a walk across the border to Chile Chico for Chilean bus connections.

Local Transport
Once you arrive at Lago General Carrera, local transportation options are limited. Small settlements like Puerto Río Tranquilo, Chile Chico, and Puerto Bertrand offer limited local bus services that connect them, but schedules are infrequent. Taxis or private transfers can be found in larger towns, but they are expensive. For exploring the Marble Caves (Capillas de Mármol) or venturing into more remote areas, boat tours are available from Puerto Río Tranquilo. However, to truly experience the diverse attractions around the entire lake and surrounding areas, a personal vehicle is by far the most practical and efficient choice.
