Very nice view and nice inland harbor. The café is tempting, but the stairs are steep...

The footbridge is closed (in November 2024) because its condition is too degraded... It's hard to say when work will be done. In the meantime, the detour via the road bridge to the northeast remains a good option (and will probably even be faster by bike because there are no steps!).

A lovely viewpoint shared with the marsh on one side and Bourgneuf Bay on the other.

We didn't want to climb up these high steps with our fully loaded bikes. The small detour along the marked EV1 route over the next weir is much easier and certainly doesn't take much longer. At the top of the stairs you'll notice the sign saying that it's only 1,547km to Santiago de Compostela! If you've made it this far, you'll probably make it to the "Field of Stars". Buen Camino!

Everyone here seems to take similar photos of the canal with its many fishing huts and boats. This place is simply picturesque. Crossing the bridge with fully loaded bikes is not advisable. It is worth taking a small detour along the marked EV1 route over the next weir. Unfortunately, we didn't have enough time to eat in the small restaurant as we wanted to go to our accommodation in Bouin.

The church was not opened for services until 1862. The gallery dates from 1922. The large organ from 1860 was bought by the municipality of La Bernerie-en-Retz in 1922 and rebuilt in 1939.

Water management is essential for life in the swamp, it is managed by the SAH. (Syndicate of the Southern Loire Hydraulic Development). 51 municipalities are affected by the regulation of these waters by the Marais Breton Vendée or Marô. There are still 3 main locks in Port la Roche and 2 in Fresne.
