After crossing some hills and the Huallaga River, you enter the very nice village of Sauce, on the “Blue Lake” shores. At only 650 m altitude water reaches 25°C; here, the environment is favorable to the development of a much diversified fauna and flora. Depending on the light and the viewing angles, water can pass from the blue turquoise to the green emerald, in a quite magic color palette. You can swim, fish, canoe and also horse ride in this place.
