In this refuge of biodiversity, it is advisable not to disturb the flora and fauna. It is therefore in green mobility that you explore the Bay while respecting the peaceful environment that reigns there. On foot, by bike or pirogue, the natural riches of the Somme Bay never cease to surprise you.

The Somme Bay offers various marked and secure bike circuits. Take the Gravelot circuit to discover the largest seal colony in France … the Avocette circuit to visit the Marquenterre ornithological reserve and observe hundreds of migratory birds … Or the Geai circuit, in the forest , which offers a completely different setting in the shade of hundred-year-old oaks and beeches.

During your stay, get ready for a big breath of fresh sea air! From your first steps on the Bay, a feeling of freedom and wonder invades you. The sky merges with the sea, the song of the birds mingles with the sound of the waves, the sand of the dunes reminds you of the eternal cycle of the tides.
