From the lake of Iléhou, if you continue on the path, it leads to the Col de la Hougade which allows you to cross over to the valley of the Pont d'Espagne and its many lakes. Count on an extra hour at an average pace to the pass." Pitou Pata" Nothing prevents!!

Large, welcoming refuge. An invigorating, cool shower during our stay. Very good meal and a great atmosphere in the evening. The caretaker was attentive. Maps, guidebooks, books, and board games are available in the common room.
