The Cadí-Moixeró Natural Park was created in July 1983 in response to the need to protect the Sierra del Cadí and the surrounding area. It has a total surface area of 41,342, ha. which makes it - together with the recently established Alt Pirineu Natural Park - one of the largest parks in Catalonia. The park stretches across three comarcas (rural districts): L'Alt Urgell, El Berguedà and La Cerdanya
The Cadí and Moixeró which are connected by the Tancalaporta pass, form an imposing mountainous barrier in the Pre-Pyrenees. They extend 30 km from west to east and divide the water courses of the rivers Segre (La Cerdanya and L'Alt Urgell) and Llobregat (Berguedà).
El Pedraforca, which is one of the most attractive mountains for climbers, occupies a special place in Catalan mountaineering tradition. It merits special attention, as it provides a beautiful and thrilling setting for climbing and is considered an authentic reference point for hikers and mountaineers in Catalonia.
