Laguna de Los Tres is one of the most visually stunning places I remember visiting in southern Argentina. From El Chaltén, the village you can stay at down below, it is possible to reach Laguna de Los Tres via an easily achievable one-day hike. From memory, it took me around three and a half hours to walk from El Chaltén to the lake, then another two hours to return back down again.
What an incredible sight it is when you first arrive at the end of the lake, with numerous blocks of ice floating on its surface, an immense glacier as the immediate backdrop, and dominating it all, the granite peaks of the Cerro Torre mountain. This is without any doubt one of the most peaceful and photogenic places in the region.
Though not a seasoned walker, I had a genuinely enjoyable time spending two nights in El Chaltén in order to explore Laguna de Los Tres and the landscapes around the mountain Cerro Fitz Roy in the surrounding area. This is a hiker's and climber's paradise; so if you are a fan of these activities, consider spending a longer period of time here.
Are you a fan of mountains and hiking? Then you'll definitely want to include a visit to the mythical Fitz Roy on your Argentinian journey. Indeed anyone passing through Patagonia would be interested in taking a detour there.
The beautiful Laguna de Los Tres can be reached by a 7.5 mile hike along a woodland trail that gets rather steep at the end. It's also the most famous trek in this part of Los Glaciares National Park. And it's easy to understand why: the area is very well-organised, and it offers less experienced hikers the option to go to the base of one of the most famous mountains in the world; the landscape is awesome, and it never gets too hot thanks to the altitude. In short, I loved it! Don't forget to climb the nearby observation tower, which offers views of the beautiful Laguna Sucia.
