About
Lagunas Altas is a lake destination in El Chaltén, the small mountain town in Argentina's Patagonia that serves as a base for hikers exploring the Fitz Roy massif. It is reached on foot, as a challenging day hike rather than a stroll, and it suits visitors who are comfortable with sustained climbing and uneven ground.
What to expect on the trail
The route climbs to a set of high alpine lakes. Along the way, the path crosses several different landscapes, so the walk does not feel repetitive: the scenery shifts as you gain height, and the vegetation and terrain change with it. The effort is rewarded at the top, where the lakes sit beneath the surrounding peaks.
The view
The lakes are known for their reflections of Mount Fitz Roy and the neighbouring summits. On a still morning the water can mirror the peaks almost perfectly, which is the main reason many people make the climb. Weather in this part of Patagonia changes quickly, so the reflections are not guaranteed, but when conditions are calm the setting is memorable.
Planning your visit
- Treat it as a full day out and carry enough water, food and warm layers.
- Wind and sudden weather changes are common at altitude, so check conditions before setting off.
- Wear sturdy footwear suited to steep and rocky sections.
Because the hike starts from El Chaltén, you can make it part of a wider stay in the town, which offers other trails, restaurants and places to rest after a long day in the mountains.
