Beautiful hike, easy to access. However, there is work underway on the dam (August 2023). The lake has been emptied and there are Algecos installed at the finish. Avoid for the moment.

The Pla de Soulcem dam is in no way a natural high-altitude pond. It was built in the early 80s. The construction of this dam drowned a vast plateau (called Pla) historically devoted to pastoralism. One of the positive aspects of this human achievement is the construction of the road which has opened up this high valley. We even considered going directly to the Principality of Andorra. Currently, the project of a summer tourist route is frozen.

Pretty lake accessible from the beginning of April this year. Note that the return made by the other side is not marked but the path is obvious.

At the foot of Mount Garias, the Alate pond is located more or less 1h30 from the Coumebière plateau and is a nice goal for a hike.
