This viewing point and the three routes which meet there can be reached by the signposted walking trail which takes 55 minutes (going and coming back), starting from the manned refuge of the Pleta del Prat, which is accessible all year round by a tarmacadamed road.
From the very top of the Pic de l’Orri, or Peak of the Orri, you can see one of the most impressive panoramas of mountains and valleys in the whole of the Pyrenees. In winter it can be reached with snowshoes.
