is a mountainous cirque in the Eastern Pyrenees located north of the municipality of Setcases (Ripollès). Its name comes from the fact that it hosts the source of the Ter river (In catalan: ull= eye Ter=the Ter river , Ulldeter = The Eye of the Ter river). United to the northeast with the cirque of Morens (and both limited to the north by a ridge that separates them from the Conflent and, therefore, from the Tet valley), it is framed by the Pic de la Dona to the east (2,704 m), the Pic de Bastiments (2,881 m) to the north, and the Gra de Fajol (formed by the Gra de Fajol de Dalt, of 2,706 m, and the Gra de Fajol de Baix, of 2,536 m), to the southwest. These are separated by the Coll de la Marrana (which separates the Gra de Fajol Alt from the Pic de Bastiments), which gives access to the Freser valley.

Great view of the Nuria Valley.
Collet de les Barraques
The site has wide views of the Serra de Montgrony and the Rigard valley, as well as the Corral Blanc refuge, parking, a picnic area and viewpoints. Several walking routes begin here, including an ascent towards Puigmal. In winter, confirm that the access track is open and passable before starting the route.
Coll de Meianell
This mountain pass, at just above 1,930 metres, stands on the boundary between Pardines and Vilallonga de Ter. It marks the transition from black-pine woodland to open grazing land and is a good place to watch birds of prey. It also serves as a starting point for walks to Puig Cerverís and Balandrau. A vehicle can reach it via the Ribesaltes–Tregurà forest track.
Salt de la Cua de Cavall
Forat de l'Embut
is a striking karst feature where a stream disappears into a network of fissures and underground passages, then emerges again beyond the mountain. The contrasting local geology explains the effect: the pale marble contains water-soluble limestone, while the darker schist does not dissolve.
Following the reference point that leaves Setcases and goes up the Carboneres stream, we find the gorges of Cossi de Batlló. Following the Setcases track to Espinavell, we can see the black pine forests of Baga de Carboners. Further on, the Baidana viewpoint, with spectacular panoramic views of Pastuira and Serrat del Dob.
