Infos & Booking


The canyon of Oscuros del Balces is certainly one of the most beautiful in Sierra de Guara. Here, the Isuala river has carved gigantic faults in the limestone, creating impressive gorges whose cliffs are visible from far away. Located near Rodellar, accessible, moderately difficult, quite short and beautiful from beginning to end, this canyon is fun and leaves no one indifferent.

In short, with its transparent turquoise waters and its exceptional underground passages, it is a real jewel that you must discover.

The descent of the Oscuros del Balcès begins with a magnificent and very wild approach walk, where you can admire the valley of the Rio Isuala but also a multitude of vultures.

The descent of the canyon itself begins with an exploration of a large chaos (huge boulders that form caves) where we find an abseil, slides and small water passages under the rocks. Then comes the highlight of the show, with a 1 meter wide, 200 meters long narrow passage topped by cliffs up to 30 meters high. The light is subdued, the atmosphere is incredible: it is the ideal moment to let yourself be carried by the water and to enjoy this unique show. A last abseiling allows you to access the most open part of the canyon and offers you some final jumps.
