Tip by

5.07 km

This unique natural site is a mixture of diverse habitats where the sea collides with the forest and where the forest merges into the dunes. There is always something to see, no matter which route you take.

Menhir de la Conche Verte

Highlight • Monument

This large menhir is 3.15 meters high. It was discovered in the 1800s and then hidden under the dunes until it was rediscovered in 1901. Excavations have shown that the menhir predates the dunes.
