The gorge is gorgeous indeed! I was there in August. Not a drop of water. Would like to go back a different season. Descent was partially overgrown and hard to find. No views there.

Over a length of three kilometres, the Èrç river has sculpted the rocks over thousands of years, creating a deep gorge that reaches between 300 and 400 metres deep. A place where the power of nature and the traces of erosion are clearly visible. The Gorges de la Frau are not only an impressive natural phenomenon, but also a witness to history. For centuries, they served as a natural passage between the Pyrenean valleys and thus tell stories of trade, travel and discovery. Today, this gorge is a central point of the Grand Traversée Ariège Pyrénées (GTAP) VTT, a mountain bike trail that makes the hearts of all adventurers beat faster. But whether you are on foot or on two wheels, the view of this narrow and steep gorge is breathtaking. It's almost like entering another world, where the rocks form the walls of an ancient castle and every stone, every tree, every curve has a story to tell. And although photos try to capture its beauty, they simply cannot do justice to the majestic atmosphere of the Gorges de la Frau. It is a place to be experienced, felt and breathed - an unforgettable natural wonder not to be missed on your trip through the Pyrenees.

Gorges de la Frau is a narrow canyon that stretches for three kilometers. This protected natural space is formed by the erosion of the Èrç river on the rock. The canyon has a depth of between 300 and 400 meters and has for centuries been a passage between the Pyrenean valleys.

The Devil's pond can be either a stopover towards the Pic Saint-Barthélemy for the more athletic, or an objective for those who hike to the Trout pond and want to push a little towards another magnificent lake.
