A beautiful, not too difficult summit on the national border 🇦🇩🇫🇷😃, but requiring some light scrambling 😃 in the summit area (⚠️ UIAA: I). Great view of the surrounding lakes 😃.

Mountain pass that separates these two areas that on one side is Andorra and the other, the French side. The same goes for the respective lakes, on one side the Fourcat lake and on the other, one of the Tristania lakes

This is the last of the lagoons that are under the feet of the peak of Tristania and consequently in its cirque. Beautiful view of the set of lakes that embrace this northern area of Andorra.

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.

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.
