Forau de Aiguallut

Highlight • Natural Monument

It is a well-known tourist attraction. The site is spectacular and the history of this sinkhole makes it even more special. The best time to visit is in spring, after the ice melts.

Salto del Pish Waterfall

Highlight • Waterfall

From Vielha, take the N-230 road towards Les and Francia. At approximately five kilometers and at the height of the village of Pont d'Arros, we will turn right to follow a paved forest track for twelve kilometers. The road is in perfect condition but it has significant percentages of unevenness and in some sections it is very narrow and it is advisable to be careful. Every kilometer a sign informs us of the percentage of slope of that section and the height gained.

Impressive waterfall in this area near what is called the Rio de Joèu (Joèu river). In the summer there are usually many people but the area is wide and cool to run through.

The Pish waterfall is one of the most popular waterfalls in the Aran Valley. It is very crowded in the summer season and is ideal for resting and recovering energy.

Tour of just an hour and a half in total duration, essential for anyone who travels to the Benasque Valley for the first time, being probably the most visited place in this valley. The Forau de Aiguallut is a chasm through which the waters from the Aneto glacier disappear to resurface again on the surface in the Val de Arán, in the Garona river basin, which flows into the Atlantic Sea in the French city of Bordeaux.
