Conche de Saint-Georges, Sandy beach in Saint-Georges-de-Didonne, France

The Conche de Saint-Georges is a broad sandy beach along the French Atlantic coast that stretches for several kilometers with fine golden sand and calm waters. The beach is well-equipped with facilities for water sports enthusiasts and swimmers.

The conches of the Côte de Beauté, including this one, formed around 8000 BC during the Flandrian transgression, when post-Würm deglaciation raised sea levels and sandy deposits filled the hollows of the Gironde estuary. In the 19th century, dunes were partly seeded to create the Suzac forest; later, the Boulevard de la Côte de Beauté and residential districts built within the forest gave the northern section its urban character.

The beach's name, "conche", comes from the local term for a sandy inlet hollowed into the limestone coast. Its northern end borders the Vallières district and the town centre, where small apartment blocks, villas and seaside chalets stand near the boulevard; further south, around La Tache, a tourist cluster of shops, bars and fast-food outlets was built in the 1970s and 1980s.

Lifeguards watch the beach from late June to early September, 11 a.m. to 19 p.m. A cycle path and a pedestrian promenade run along the Boulevard de la Côte de Beauté, linking Royan, the Vallières district, the town centre and the Pointe de Suzac. The southern end, bordered directly by the wooded dune, is the least built-up section.

The Rivau de Chenaumoine, a thin stream rising in neighbouring Semussac, reaches the Gironde through a pipe laid under the beach at La Tache. Bathers walk over it without noticing; only the name of the spot recalls it.
