A trip to Laguna de los Tres near Mount Fitzroy in Los Glaciares National Park is in a word, memorable. The lake is accessed only by hiking, which can be split into two days or rolled up in one somewhat more challenging day. Tent camping is available at nearby Campamento Poicenot.
For the two-day trip, the campsite is a steep, five-hour roundtrip hike from El Chaltén. Many people make camp here to set out early to Laguna de Los Tres for a glimpse of the early morning sun on the turquoise lake set among the mountains. You’ll want to allot time to spend at the lake enjoying the view. To make the trip in one full day, set out early from El Chaltén for an eight-hour hike. This option skips the early morning views of Mount Fitzroy from the campsite.
