The park, of just over 14,000 hectares (34,600 acres), spreads high up in the mountain, around the enclaves of Núria and Ulldeter, and completes the Natural Protected Spaces of Catalonia System.
Limiting to the North with France and with the Catalan Pyrenees Regional Natural Park, the municipalities of Planoles, Queralbs, Ribes de Freser, Pardines, Setcases, Vilallonga de Ter and Molló have part of their territory within this park.
The landscape and natural wealth of the Ter and Freser high valleys is exceptional. Crowned by emblematic peaks, such as Costabona, Bastiments, or Puigmal, the park is a sample of the natural alpine and sub-alpine systems typical of the high Eastern Pyrenean mountain.
During the snow melting season, extensive farming is the most widespread main activity. Leisure activities and nature tourism are having a growing presence lately. The main objective of being declared a Natural Park is to reconcile the conservation of the natural and cultural heritage with the uses which are already in place.
