Hidden natural freshwater pools where you can swim and sunbathe, with access via a route through rocky valleys. Of course, the water is very cool when you come down from the mountains.

This beautiful stone bridge, which crosses over the Tres Cerros stream, is located in a spectacular setting. It is a much less crowded area than Los Pilones, and is part of the Carlos V hiking route. There are some pools of transparent water in which to relax your feet before continuing the march.

This beautiful viewpoint has a small booth, benches and various information panels. Although in the rainy season it is easier to see, on clear days you can see the Manto de la Virgen waterfall in the distance. It is located less than a kilometer from Los Pilones.
