Just below the Pico de Maubèrme and where at its feet is the Lac de Montoliu is this small shelter that is now a mountain shelter in case of an unexpected storm. It's worth getting there to see him and the views he offers.

The road navigates along the edge of the hillside, from where you get sensational views of the valley. If you leave Bagergue behind you you face slopes of up to 16% until you reach the top of the mountain.
