Very beautiful chapel, recently restored after a fire in 2022. The panorama over the entire Monts d'Arrée, the sea and the crests of the Montagnes Noires is magnificent.

Exceptional views from the summit. You can reach the summit by racing bike, although the last part is a bit gravelly.

One of the special highlights in this area. An almost balanced granite rock that you can rock at a certain point - provided you have enough strength. Unfortunately, there are often larger hiking groups with informative guides here...
