We leave El Chaltén by car and enjoy views of huge Lenga trees, small waterfalls, and glaciers as we travel 37 km along the scenic Río de las Vueltas to its source at the Lago del Desierto (Desert Lake). Once we arrive, we will take a short, low-difficulty hike to the Huemul Lagoon to appreciate the emerald color of its waters and the glacier that descends towards it from the Vespignani range. 

Back at the lake, we board a catamaran for the 45-minute journey to its northern end. From here, we can choose to do another short hike to the Sentinel viewpoint, which offers a panoramic view over the entire length of the lake, the Vespigniani mountain range, and the north face of Mount Fitz Roy. 

We hike back to our start point with a 14km low-difficulty walk along a path that borders the Lago del Desierto. Our vehicle will be waiting there to take us back to El Chaltén.
