This protected Catalan natural park has the largest numbers of flora and fauna of interest in Europe.
It has a surface area of 41.342 hectares, one of the largest nature parks of Catalonia in conjunction with the new Nature Park of the Alto Pirineo. It is includes three counties: Alt Urgell, Berguedà and Cerdanya.
The two grand ridges of the Cadí – Moixeró, united by the pass called Tancalporta, make up an incredible mountain barrier which runs from the west to the east along 30 km in the water divide of the Segre (Cerdanya – Atl Urgell) and the Llobregat (Barcelona).
Of significant importance is the Pedraforca mountain as it is one of the most visited mountains and is steeped in Catalan alpine tradition as it offers climbers a perfect combination of risk and beauty. It is one of the symbols for hiking in Catalonia.
