We will do a trekking of 10 km in total (5 km one way, 5 km back), to the emerald lagoon. This tour has a low level of difficulty, but the weather conditions of snow, wind and cold can vary the difficulty. Once in the Esmeralda Lagoon, a mountain refuge awaits us to enjoy a gourmet lunch in the heat of a salamander. After enjoying an afternoon in the mountains, we will return along the same path enjoying the surrounding landscapes. This activity is a low difficulty mountain trekking.
