In Guenroc, trails along the Rance sit alongside a distinctive architectural and local history. For trip planning, the different types of trails, the view from Le Rocher Blanc and buildings from different centuries are particularly interesting. You can focus on the river landscape and nature, or include more history and architecture.
Trails along the Rance and nature
The Entre Diable et Rance circuit follows the Rance for about 3.5 kilometres. The Bords de Rance trail runs from the viewpoint at the Rophemel dam along the river to Beaumont Bridge and is just over 5 kilometres long. In terms of length, Entre Diable et Rance is the shorter of the two routes. The trails also differ in form: the first is explicitly described as a circular route, while the starting point and destination of the Bords de Rance trail are specified. This gives you a concrete basis for choosing according to route length and type.
Protected natural sites lie along the Bords de Rance trail, where the fauna and flora are also preserved. Guenroc also has a botanical educational trail and explanatory panels. If you are interested in plants and the natural environment, you can include this nature-focused theme in your trip planning alongside the riverside trails.
Le Rocher Blanc and the Rophemel dam
At the foot of Guenroc lies the natural site of Le Rocher Blanc: a white quartz vein on the edge of the granite massif known as BĂ©cherel. From the viewpoint at Le Rocher Blanc, the view extends across the northern plain to 16 church towers. The site has been listed as a historic monument (Monument historique) since 1913. Here, a striking geological feature meets a sweeping view across the plain.
Another viewpoint is located 26 metres above the Rophemel dam. The dam’s reservoir holds 5 million cubic metres of water, and the Bords de Rance trail begins at the viewpoint. Guenroc therefore offers different viewpoints and landscape features side by side: the quartz vein and northern plain at Le Rocher Blanc, and the dam and riverside trail at Rophemel.
Church, château and local history
The present-day Church of Saint Gervais and Saint Protais was built in 1465 to replace the previous church. Many of its Flamboyant Gothic features are characteristic of the Dinan area. It has been listed as a historic monument (Monument historique) since spring 2024. The church is open to the public; check current opening hours before your visit. Cultural events are held there, including classical, choral and jazz concerts, history or heritage conferences, and exhibitions. The events programme may change.
The Château de la Roche was built in 1830 on the site of a manor house mentioned as early as the 15th century. The château includes a Neo-Gothic chapel, built near the pond in 1889. The use of Falun limestone also gives the façades in Guenroc a distinctive touch.
Guenroc also developed into an important centre for flax growing and processing. This economic and artisanal tradition adds another aspect of the town to its architectural history.
