Lago General Carrera: A Brief Guide

Lago General Carrera is one of the most surreal places to visit in Chile, if not the whole of Patagonia.

Surrounded by the peaks of the Andes Mountain range, the turquoise waters have a surface area of over 1800 square kilometres.

The glacial lake spans both Chile and Argentina with a little over half in Chile. While it’s called Lago General Carrera in Chile, the Argentinians call it Lake Buenos Aires.

Once the Carretera Austral was built – the road connecting Puerto Montt to Villa O’Higgins – access to the Chilean side of the lake opened up.

And with it, a world of opportunities for outdoor lovers.

From our week exploring the area around Lago General Carrera, we learnt a few invaluable lessons. From where to stay to why you should rent a car, knowing the best time of year to visit and things to do around the lake, this post has you covered.

Things to do around Lago General Carrera

The Aysén region of Chilean Patagonia is breathtaking. Remote, sparsely populated, adorned with snowy peaks and deep fjords, there’s no shortage of outdoor activities to do.

Marble Caves

The Marble Caves are one of the highlights and main tourist attractions around the lake. A short but bumpy boat trip from Puerto Rio Tranquilo carries passengers out to a series of caves and rock formations.

Centuries of wave and wind erosion has revealed the colourful marble beneath. Visit in the early morning to experience the colours in all their glory at the Marble Cathedral.

How to get to Lago General Carrera

Given its size, you might think this is a pretty broad question. In reality, there’s only a few small towns around the lake and because they’re so remote, transport options are fairly limited.

The best way to get to the lake is as part of a Carretera Austral road trip. This way you can take your time and hang out in the laid back towns along the shore. 

With a car, you can drive the circuit from Puerto Ingeniero Ibañez on the northern shore to Chile Chico, via Bahia Murta, Rio Tranquilo and Puerto Guadal.

If you don’t have your own vehicle, hire a car. It’ll give you way more flexibility and freedom than public transport.

If you rely on public transport, you can get a bus to Puerto Rio Tranquilo from either Coyhaique or Cochrane. Take a look at the BusBud website for schedules and ticket prices.

If you want to go all the way to Chile Chico from the north, it’s possible to get a ferry from Puerto Ingeniero Ibañez.

Heading north | Stick to the Carretera Austral. Plan to hike Cerro Castillo and visit Coyhaique. The San Rafael Glacier in the Patagonian Northern Ice field is a fabulous, albeit extravagant day trip too.
