This is a semi-circular route which starts from Pas de la Casa Town and allows you to discover the Abelletes lake. The climb begins along the Port d’Envalira road until the Costa Rodona zone, from there you take the track to the left next to the ski station bar. Follow the track up to the Abelletes lake.
From there, the views of Pas de la Casa, Port d’Envalira and the Ariege region of France are exceptionnel. The return is via the same way, but it finishes with the descent of the ski slopes from the Costa Rodona zone down back into Pas de la Casa.
