Panticosa Spa is a glacier hole in the middle of Spanish Pyrenees; a granite hole rounded by peaks more high than 3000 meters. It has 4 lakes at less one hour of walk, 11 at less 2 hours and circa 80 at 4 hours! And has a multitude of species of trees, shrubs, flowers and mushrooms that grow along its trails. I propose you to visit some of the most unknown, and of greater diversity, where we will learn to identify those species that serve to heal or eat. A comfortable and entertaining tour, in which we will lack time. There is a specific path. There are few loops between a forest of maples, Scottish pines and black pines to the first fields, meadows and a small trough where the forest is closed again over streams and springs water (30 ') to ascend to a small pass, already in sight of the first lake of the Lumiachas (1 hour; and the time to take photos, identify plants ..) After, we'll return along the waterfalls of Caldarés river (1:30 am) to the Casa de Piedra refuge. We'll rest and review what we have found, resolve doubts and take a walk to the hot spring water and the lake to end!
