Carretera Austral, Aysen

An exclusive proposal of Walk Patagonia to travel the Carretera Austral, famous for its surreal landscapes, its picturesque localities, and its pristine nature.

Day 1
Puerto Tranquilo

Arrival in Puerto Tranquilo, from Balmaceda Airport (Chile) or from Los Antiguos, crossing via Chile Chico (border with Argentina).

Overnight: Hostal El Puesto, or similar.

Day 2
Excursión a las Capillas de Mármol

We can visit these interesting geological formations by boat or kayak. The kayak option, which takes half a day, can be done in the morning or afternoon, based on the weather forecast.

The rest of the day is free to rest or take a stroll along the seafront.

– Overnight: Hostal El Puesto, or similar.

Day 3
Guided trekking in Valle Exploradores

After breakfast, we depart with our guide towards Valle Exploradores, where we venture into the forest up a steep hill until reaching a lookout point offering marvellous views of the Glacier and Monte San Valentín, the highest peak in Chilean Patagonia. Continuing a little further, we’ll enter a valley flanked by narrow, vertical walls, and get closer to the Glaciers jutting from the Northern Ice Field.

We’ll choose a spot with a fine view for lunch, before retracing our steps back to our vehicle and return to our hostel for a well-earned rest.

– Overnight: Hostal El Puesto, or similar

Day 4
Caleta Tortel

Today, we travel down another section of the Carretera Austral to the picturesque town of Caleta Tortel, nestled in a zone of archipelagos with endless islands, channels and estuaries, and rugged mountain ranges crowned by glaciers.

In the afternoon, we visit Isla de los Muertos (the Island of the Dead), which can also be visited by boat or kayak.

– Overnight: Hostería Baker, or similar.

Day 5
Trip to Villa O’Higgins

We have a free morning, with an optional short walk in the surrounding area and a small ascent (rewarding us with nice views).

Candelario Mansilla is still today an operating farm, inhabited and run by the direct descendants of the founder.

  • This trip can be done in a hire car or through a combination of private transfers. Please ask.
  • For the crossing between Candelario Mansilla and Gendarmería Argentina, horses can be hired to transport luggage. The horses must be booked in advance.
  • If you have any extra days spare, we recommend planning a longer stay in Villa O’Higgins or El Chaltén, where you’ll have the chance to do numerous trekking circuits and mountain activities.
  • This circuit can be combined with a later journey to or stay in Torres del Paine National Park. Please ask.
  • This journey can also be done in reverse. Please ask.

We do not recommend booking a flight with less than 5 days’ difference between Day 7 and the day of the flight (i.e. the flight would be day 12 or later), given that the boat crossing from Candelario Mansilla to Gendarmería Argentina is heavily dependent on the weather, and is often cancelled due to strong winds.
