Finally, the most emblematic trail of Glacier National Park: is the Laguna de Los Tres (‘Lagoon of the Three’). It is a walk of about 6.2 miles, passing through trails surrounded by lenga and ñire forests, allowing the admiration of the silhouettes of the mountains. The difficulty of this trail reaches its peak at the final portion, with a strenuous climb of a little over 540 yards. The reward is high: a perfect setting to appreciate the three mountaintops that give the lake its name: Saint Exupery, Poincenot, and the imposing Fitz Roy (2.12 miles high).
