Moderator update on 10/08/2020: Please note that reviews of this hike indicate that the access road to the dam is closed every summer.
The path is well marked.
(S/E) Below the dam, take the southbound path (GRP® du Tour du Carlit - yellow and red markings).
(1) Turn left (east) after 500m. Go around the "sagnas" (marsh lake) and reach an intersection about 50 metres from the access road to Lac des Bouillouses.
(2) Turn right and climb into the woods. Follow the signs. Climb for about 10 minutes, walk alongside another "sagnas" and then, after a flat section, descend to Estany Llarg.
(3) Walk along the lake for a short distance, then turn left onto the path to reach Estany Negre.
(4) Walk along the lake, then turn right away from it and climb up to Estany de la Pradella.
(5) From here, the return journey follows a very busy route. Join theGR®10(white and red markings) and follow it to the right for about 400m.
(6) At the shelter, leave theGR®10, which branches off to the right, and continue straight ahead to reach a wide track. Follow this track to the right and continue until you reach the junction with theGRP® du Tour du Carlit.
(7) Continue straight ahead.
(1) Leave the path you took on the way up on your right and continue straight ahead to return to the starting point (S/E).
hike rated easy. The trail starts across alpine pastures and leads to a wood near the car parks. From there, the path is signposted.
