The natural surroundings are the highlight of this high mountain trail passing through the Bahns de Tredòs area and the upper Aiguamòg valley. It borders the Aigüestortes National Park and Estany de San Maurici.

Leave Salardú and go up the paved track to Banhs de Tredòs. The track, which is dirt here, continues to rise through a beautiful natural area and reaches the Pruedo plain (2050 m) surrounding Tuc dera Salana, which is on your left.

The descent to Valarties is quite fast, and on the valley floor you’ll find the paved road again that will take you to Arties. From there, you’ll just have to head towards Gessa and Unha on the GR 211 and go back to Salardú.

Los Banhs de Tredòs is a unique place (the highest hot springs in Europe), where you can enjoy this wonder of nature. From the Pruedo area, the views of Montardo and the Rius valley are the most spectacular you’ll see in Arán.

Finally, the trail passes through Arties, Gessa and Unha where you can take the opportunity to explore.
