A granite formation weighing more than 45 tonnes that can be moved with one hand makes an unusual impression in Dettey. There is also the Romanesque church of Saint-Martin and a panorama with views across several landscapes. This gives you a range of themes to focus on when planning your visit: geological features, architectural history and outdoor activities. A specific challenging hike can be distinguished from the hiking and mountain-biking routes available at the panorama.

Granite, Panorama and Natural Landscape

The Pierre croule is a granite formation in Dettey weighing more than 45 tonnes that can be moved with one hand. The combination of its considerable weight and this mobility makes it an unusual geological feature. There are also granite rocks at the Panorama Circulaire de Dettey. From there, the view extends across the Morvan, the Monts du Beaujolais and the Massif Central. Le Profil de Napoléon is also called Bonnet du Diable, depending on the viewing angle. The two names refer to the same formation; the name used depends on the angle from which it is viewed.

Dettey is one of the municipalities in the natural area of Uchon et environs. The area is characterised by spectacular granite boulder fields, oak and beech forests, bocage landscapes and numerous small ponds. The landscape description therefore includes not only striking rocks, but also forests, bocage and ponds. The church of Saint-Martin in Dettey is also located in the Morvan Regional Natural Park.

Romanesque Architecture at Saint-Martin

Dedicated to Saint Martin, the church of Saint-Martin dates from the late 11th or early 12th century and is Romanesque. Its layout consists of a single nave, a bay with a groin vault beneath the bell tower, and a semicircular apse. The apse contains a Romanesque round-arched arcade on small columns with undecorated capitals. This describes both the layout of the building and the design of the apse. The date places the church in its historical context, while the nave, vault and apse bring its architecture to life. For visitors interested in Romanesque architecture, Saint-Martin combines historical context with a clear description of its architectural features.

Hiking and Other Outdoor Activities

Hiking, mountain biking and GTMC routes are available from the Panorama Circulaire de Dettey. The Circuit de la Pierre que Croule is a separate option: this challenging hiking trail is 15 kilometres long and starts in Dettey. These are two distinct outdoor options: a specific hiking trail with a stated distance, and the hiking, mountain-biking and GTMC routes mentioned at the panorama. If you are planning around a specified hiking distance, the Circuit can be considered as a separate option; the panorama offers a choice of different activity types. This lets you consider the specific hike separately from the other options at the viewpoint.
