About Plage du Plat Gousset, Granville
The main town beach below Granville's promenade. The Bay of Mont-Saint-Michel has some of the biggest tides in Europe, so the beach can almost vanish at high water and is often windy. Collectors report glass on several beaches along this coast, from Donville-les-Bains through Granville to Carolles.
