A great viewpoint! I rode up by bike and felt like I was in the Alps, but we're at 341m altitude, not 1600m!

The chapel originally dates back to the 17th century. A visit is definitely worth it – the view is simply fantastic!

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.

Church of SANT-SERVAIS Impressive ensemble consisting of church, ossuary (now museum) and adjoining triumphal arch. The church also reveals numerous original carpentry works with decorations, such as the theatricality of the interior or the literally fantastic stonework that adorns the façade.

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