The Nahuja belvedere allows you to take in the entire Cerdanya ditch in one glance. The Carol glacial valley offers itself to the eye from another perspective. We can also observe there, dug into the plateau carrying the Carlit ponds, the glacial valley of Angoustrine. The mountains that surround it have frozen the shape of the tongue of ice that came from it. These reliefs show several generations of moraines, recognizable by the state of alteration of the material of which they are composed. Towards the West, the gaze flees towards the Spanish Cerdanya. The effects of the Têt fault extend to the surroundings of Seu d'Urgell.

Don't hesitate to take a little detour via the Popy belvedere while crossing Osséja. The small path called “Sentier des orgues” which goes up towards the Popi allows you to tell the story of the Cerdagne ditch. It winds through *badlands*, areas where erosion is still very active, dug in the deposits torn from the reliefs and deposited at the foot of the reliefs. These orange deposits are those of the Miocene of Cerdanya, named after the geological period in which they were deposited. These are fine, reddish deposits alternating with beds of pebbles and schists.

The lake was created in 1955/60 and is rich in fish (trout). The beautiful hike there is suggested by the local tourist office (PR 2 - LE LAC DU PASSET).
