Discover Guenroc: Trails, Landscapes and Heritage

Explore Guenroc through two themes: trails and landscapes along the Rance, and architectural and local history. For planning your trip, the trail length is one practical difference to consider; there is also a botanical trail, a striking quartz outcrop and historic buildings. This can help you decide whether to devote most of your time to hiking, taking in the scenery or exploring the architecture.

Hiking along the Rance

The Entre Diable et Rance circular trail follows the Rance for about 3.5 kilometres. The Bords de Rance trail is just over 5 kilometres long and runs from the viewpoint at the dam along the river to Beaumont Bridge. Entre Diable et Rance is therefore the shorter loop, while Bords de Rance is the longer route along the river.

Protected natural sites lie along the Bords de Rance trail, where preserved flora and fauna can also be seen. Guenroc has a botanical trail and explanatory panels. The trail and panels offer a botanical focus, while the Bords de Rance trail takes you past protected natural sites and preserved flora and fauna.

Scenery and viewpoints

Le Rocher Blanc is a natural site at the foot of Guenroc: a white quartz vein on the edge of the granite massif known as Bécherel. From the viewpoint at Le Rocher Blanc, you can see across the northern plain as far as 16 church towers. Le Rocher Blanc has been listed as a historic monument since 1913.

The reservoir behind the Rophemel dam holds 5 million cubic metres of water. A viewpoint stands 26 metres above the Rophemel dam. These details about a large body of water and the height of a viewpoint complement the routes and landscape features.

Church, château and local history

The present-day Church of Saint Gervais and Saint Protais was built in 1465 to replace the earlier church. Its architecture is characterised by numerous Flamboyant Gothic features typical of the Dinan area. The church has been listed as a historic monument (Monument historique) since spring 2024. It is open to the public; check current opening hours before your visit.

Events associated with the church include classical concerts, other singing and jazz concerts, history- or heritage-related talks, and exhibitions. Individual event programmes may change.

The Château de la Roche in Guenroc was built in 1830 on the site of a manor house mentioned since the 15th century. The château includes a neo-Gothic chapel, built near the pond in 1889. Falun limestone enriches the façade design in Guenroc. Flax is also part of the town’s history: Guenroc developed into an important centre for flax cultivation and processing.

The Fontaine de Jarnouen is also associated with an earlier tradition: its water was once believed to cure skin diseases.
