The giant of the Sierra!

Located in the upper part of the Alcanadre river we find a canyon whose dimensions will not leave anyone indifferent, the Gorgas Negras. Imposing is, together with Mascún, one of the most emblematic descents of the Sierra de Guara.

This canyon holds astonishing corners from straits full of pots to long and placid badinas, all in a harsh and wild landscape.

The Gorgas Negras is a water descent for experienced canyoners, as it presents a certain technical difficulty and requires significant physical resistance due to the long duration of the approach and return marches, as well as the long water descent.

During its route, great jumps, siphons, rappelling, waterfalls, successions of kettles, chaos of blocks, natural slides and flooded corridors are combined. To all this we must add an approach walk passing through the Losa Mora dolmen and the abandoned town of Nasarre, witness to a way of life that has already disappeared.

Those canyoners prepared for the descent will be able to enjoy a great day meeting the giant of the Sierra de Guara.

Description of the activity

At the established departure time it will be necessary to be at the door of the office with your own vehicle to collect the material and meet the guide who will accompany us throughout the tour.
Taking into account the dimensions of the ravine, it is necessary to get up early!
Remember your swimsuit, food, water and sneakers!

From the office we will follow the guide’s car to the parking lot where the activity begins.

From there we will make a long approach march passing through Losa Mora and the abandoned town of Nasarre until we reach the river.

Once in the water we will put on the neoprene and enjoy the descent!
