Saint-Ouen-en-Belin is a rural commune surrounded by meadows and forests. Walking trails lead through woods and valleys and pass close to Étang de Claire Fontaine. The area also has historic buildings and memorial sites. This offers two distinct focuses for a trip: spending time outdoors and taking a closer look at local architectural and commemorative history.
Hiking: understanding trail distances and times
The SO1 walking trail starts at the Salle des fêtes l’Audonienne. The 2025 route leaflet gives its length as 7.4 kilometres; a variant extends the route to 7.8 kilometres. SO1 is marked in yellow, and the estimated walking time is one hour and 45 minutes to two hours. The variant is 400 metres longer. The distance and time estimate should be considered separately: the estimated duration is given for SO1.
The Circuit L’Audonien SO2 is a 14.8-kilometre circular walking trail—twice as long as the 7.4-kilometre SO1. Comparing the trail lengths helps you choose how much time to set aside, without rating the routes by difficulty or walking time. If you plan to take one of the routes, check local trail conditions before setting out.
Nature at the pond and in the permaculture garden
Étang de Claire Fontaine is also designated as a natural area: an INPN form dated 12 June 2024 lists it as a continental ZNIEFF type 1 site. Its national identification number is 520006736 and its regional number is 40200002. Along with the trails through woods and valleys, the pond is a distinct natural feature to help orient yourself around the area.
Workshops run by CBON CBIO in Saint-Ouen-en-Belin offer another way to engage with nature. They provide an opportunity to discover the flora and fauna of a permaculture garden. Check the specific workshop arrangements with the provider before travelling. Alongside the landscapes along the walking trails, you can also choose an activity focused on plant and animal life.
Architectural history and memorial sites
The Manoir de la Poissonnière dates from the 15th century and has been classified as a Monument historique since 1977. A large farmyard and moats surround the building. The chapel attached to the main building is designed in the Flamboyant Gothic style; its wall paintings are still there but have faded considerably. The farmyard, moats and chapel offer different perspectives on the historic manor’s architecture.
Access is subject to a time-related restriction: the 2025 visitor leaflet lists the manor as privately owned and notes that it was not open for visits that year. If a visit is part of your plans, check current access arrangements before travelling.
The church of Saint-Ouen-en-Belin also has a clearly dated architectural history. A lightning strike destroyed the previous church on 7 July 1896; it was rebuilt in the Neo-Romanesque style in 1901. The Plaque d’Averton in the church is an element of heritage interest. In the square beside the church, a war memorial topped by a stone eagle commemorates the residents of Saint-Ouen-en-Belin who died for France.
