Most of the trail is muddy so we will provide rubber boots and horses toto carry our stuff (and anyone who wants to rest). After breakfast, we start walking to La Muralla for lunch (10 km hike), where we can find several types of vegetation during the trail. Afterwards, we will continue to the pass, “La Fila” (7 km hike), at 3,700 meters, and continue our descend into the forest, arriving to the shelter at 4 pm (8 km). We will leave all the gear, set everyone in their rooms and take a quick hike to the top of the hill to get a first impression of the lake. At 6.30 pm we will eat dinner and then everyone can relax and prepare for the next day.
