Beauvoir-Sur-Mer can be explored through a range of different themes: the history of Saint-Philbert Church, the wetlands of the Marais Breton Vendéen, Port du Bec and the Passage du Gois, which is governed by the tides. When planning your trip, the main consideration is which of these themes you would like to focus on. The church’s architecture and monastic history span long historical periods, while a visit to the Passage du Gois depends on the state of the tide. Nature watching and activities at a farm also depend on the season and programme. These differences can help you set realistic expectations for your stay.
Marshland and Nature Reserve
Beauvoir-Sur-Mer lies in the Marais Breton Vendéen, a landscape of wet meadows, reed beds, polders, canals and tidal creeks. The Marais du Bout de Sac regional nature reserve was established within the commune on 26 September 2025. It provides a habitat for black-tailed godwits, common redshanks, natterjack toads and the rare dragonfly species Leste à grands stigmas. This also makes the area interesting for travellers who would like to include nature watching in their trip; sightings may vary depending on the season. Check the reserve’s current access rules before visiting.
Saint-Philbert Church and Its History
Saint-Philbert Church stands precisely on the site where Saint Philbert had a Benedictine monastery built towards the end of the 7th century. The church’s main structural elements were built between the 11th and 12th centuries. This means two historical layers can be distinguished at this site: the founding of the monastery and the later construction of the church’s principal elements. Those interested in religious buildings and medieval history will find a tangible reason here to explore the site’s long development.
Port du Bec and Passage du Gois
Port du Bec lies at the mouth of the Étier du Dain canal between Bouin and Beauvoir-sur-Mer. Because its pontoons are supported by wooden piles, it is nicknamed “Port chinois”: the interwoven rows of piles are reminiscent of harbours on the China Sea. There are bars, restaurants and shops at the port; local offerings may change. At high tide, you can watch the oyster farmers at work there.
The Passage du Gois is a 4.150 km-long road that is submerged at high tide. It connects the island of Noirmoutier to the mainland and becomes visible twice a day. At high tide, it is covered by about 1.50 to 3 metres of water, depending on the tidal coefficient. It can be crossed from 1 hour 30 minutes before to 1 hour 30 minutes after low tide; safety notices are posted at the entrances. If you plan to use the passage, check the latest tide forecast beforehand and follow the notices on site.
Meet Animals and Explore the Surrounding Area
La Maison de l'Ane is an educational farm and animal park in the Marais Breton Vendéen. You can meet various donkey breeds and other farm animals there. Donkey rides are offered on the grounds for children weighing up to 35 kg; donkey walks outside the grounds are available by reservation. In the afternoon, there are demonstrations of milking jennies and processing donkey milk into soap. Their timing depends on the seasonal programme. Before travelling, check the current visiting conditions and applicable age and weight requirements; a reservation is required for walks outside the grounds.
An orienteering course can be completed on foot or by bicycle, alone, with friends or with family. Check the latest access information before setting off.
