The great majority of local rivers and ravines with an important flow rate are born in the north face of the Beceite Mountain Passes: the Matarranya, the Algars, the Ulldemó or the Canaletes. In their headwaters there are exceptional rock and water formations and, in this case, the Canaletes from the Ventador on has one of the most spectacular stretches of river to practice initiation canyoning with water from the Beceite Mountain Passes. These activities must be booked in advance, the rules and materials necessary for the activity will be explained and supplied to all participants. The activity is half a day long. We will meet the group in the village of Arnes, where we will try on the wetsuits and helmets. We will have to carry a bathing suit, a towel and mountain shoes. Following the instructions of the guide we will head to the beginning of the ravine and… enjoy!
