The route connects the municipalities of El Pont de Suert and Vall de Boí on foot, following the course of the Noguera de Tor and Noguera Ribagorçana rivers. The Camí de l’Aigua (Water Trail) follows old paths that once connected the villages of the valley, including traditional roads, livestock trails and bridle paths.

In total, the route covers around 29 kilometres, with water as its common thread, an element that is ever-present throughout this region. The trail begins at the Escales reservoir, at the Font de la Mena spring (El Pont de Suert), and ends at the Caldes de Boí Spa. The full route is considered difficult, although it can also be completed in sections.
