Guichen walks

A very pleasant hike. First section at the top of cliffs, with lovely views over the Vilaine river and the site "Moulin du Boël". Cross a shady woodland, then return along the towpath. To avoid as much as possible passing along the military site's fence ("Le Celar"), this new description uses a slightly more technical part of the GR®.

A short hike between ponds and following the Seiche river.

The first part of this hike takes you into deep woods. Then you will discover the archaeological site of the medieval castle of Boutavent. Continue this hike through open areas with beautiful panoramic views and steep ascents and descents to reach the Étang de la Chambre au Loup.The return journey takes you back up a steep, open and rocky climb with breathtaking views. :!: 9.07.2025: The signposting has been changed from blue to yellow.

A short hike in the Rennes forest along shady forest lines and paths through the forest alongside the Caleuvre stream. This easy trail is particularly beautiful in early spring, when the beech trees have young, light-green leaves, or in autumn, when the leaves have turned yellow and red. It takes you along the old water supply line that brought water from the Minette (a tributary of the Couesnon) to Rennes.

A pretty, easy, well-marked walk passing by a chapel, the Château du Gué, the Ancienne Fonderie de Servon-sur-Vilaine, the Oratoire Saint-Mathurin, the Vilaine, the old mill, the protected Pas Davy site, the greenhouses (mainly tomatoes) and the calvary. The return journey takes you along a leafy driveway through a housing estate.

A short trail in Brittany’s countryside with a section along the Veuvre that winds before flowing into Chevré lake. Do not miss the small Roman bridge with its stone arches.

Circuit exploring the 11 locks of the Canal d’Ille-et-Rance.

The Couesnon river meanders through a deep valley, home to ancient mills.
