The optional El Chalten circuit trek is dotted with incredible panoramic views and offers an incredible trekking experience. The trailhead is on the edge of town, right by the National Park Administration Office. After 1 hour of walking in a slight ascent through lovely forests of beech and ñires, you reach an open area, called "Pampa de las Carretas" with a wide and beautiful view of Mount Fitz Roy, Torre and Huemul. Then the trail starts to go into the thick forest, where you can probably identify many birds that inhabit the area. Emerging from the forest we find ourselves in a barren mountain landscape, and here we can see many marine fossils - ammonites and belemnites that are 100 million years old.
Once at the viewpoint, we have a spectacular view of almost the entire area: the Fitz Roy river canyon and Cerro Torre Glacier, the lagoons Madre and Hija, the Fitz Roy, and Laguna Condor. In the other direction, we can see the Viedma Lake, and the valley of the river Tunel, with the Windward Passage, the gateway to the Continental Ice.
