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!!

For your information, historically this was the arrival station for the cable car. It operated until the installation of the television and radio relay. After a storm, it's not uncommon for the relay to go into standby mode. TDF has a contract that runs from Monday to Friday. In case of a power outage, the weekend is reserved for reading or playing board games.
