Lagune du Vorlenn

Nestled between two pebble beaches (double tombolo) that link the Pointe de Séhar to the mainland, this coastal marsh is characterized by its shape and changing salinity with the tides. Originally, it was covered by the tide twice a day.

In the 1970s, the marsh was partly filled in, but a 6,000 m² surface area remains. The shallow, brackish water is home to a unique flora and fauna. Sea and freshwater plants live side by side: ruppia maritime for the former, phragmites for the latter.

The sea pond is a wintering and nursery ground for several species of birds. At the end of the 19th century, a road was built on the northern spit to promote the development of the port of Locquémeau, which was booming with the sardine industry.

Port parking lot: access to the observatory and information panel. Picnic area.

Nature outings and guided tours throughout the year. Full program available from the tourist office.
