The natural sub-region of the Corberes is located to the south of the massif of the same name, divided between the Fenolleda and the Rosselló, in addition to two villages of the Aude that are located on the southern slope: Tuissan and Pasiòls.

In geographical terms, this entire territory forms a single unit, which is called Corberes in Catalan. This natural sub-region occupies, in Rosselló, most of the Ribesaltes canton up to the Ròbol river, with the plateaus and depressions of Ópol, Vingrau and Talteüll and the Estagell basin, which includes Estagell, Montner and the Tor de França and it includes the northern end - the mountainous part - of the entire valley of the Ribera de Mauri, including Querbus and the grade of Mauri, the gorges of Galamús and the north of the municipality of Mauri, but not the town, which is in the Valls de la Fenolleda.

The sub-region of Roussillon is devoted mostly (more than 90% of the land) to vineyards, and has around five thousand inhabitants (almost half of a century ago). Human remains from around 400,000 years before Christ have been found there and a prehistoric museum has been set up in Talteüll.
