Rather than going around the marshes, why not take a walk right in the middle.

The Salaire Bridge on Île d'Olonne in Vendée was built in 1758 by Lord Julien Gallouin to replace a ferry that had become inadequate and dangerous, facilitating passage to the region's salt marshes. This wooden bridge, supported by cut stone pillars, replaced a paid ferry service used by farmers and salt workers for several centuries. Over the years, the bridge suffered from a state of disrepair, which a property owners' association helped to preserve in the late 19th century, before a major reconstruction was completed in 1935. Further renovations took place in 1980, followed by a complete reconstruction in 2018, which preserved its historic appearance by reusing the original materials.

Be careful, the track is not paved and not necessarily very wide in places. Otherwise, it's a real pain :-)
