Plage de Gatseau, Sandy beach in Saint-Trojan-les-Bains, France.
Gatseau Beach extends along 500 meters of coastline with gentle slopes, facing south at the southern end of Oléron Island.
The beach developed near Saint-Trojan-les-Bains, which emerged as a seaside resort during the growth of maritime tourism in Charente-Maritime.
Local residents and visitors gather at Gatseau Beach for traditional coastal activities including shore fishing and sailing throughout the summer months.
The beach provides monitored swimming zones from July to August, with lifeguard stations, restroom facilities, and dedicated parking spaces near the shore.

The Atlantic beaches of New Aquitaine extend along the coast, featuring natural spaces for water sports, swimming, and leisure. These beaches alternate between fine sand, pine forests, and dunes, with varied activities at each location. Multiple swimming areas include seasonal lifeguard services and basic facilities such as showers and parking.
Oléron Island, the largest island in mainland France after Corsica, features a military, maritime, and natural heritage reflecting its strategic position facing the Atlantic Ocean. This Charente island, connected to the mainland since 1966 by a nearly three-kilometer-long bridge, houses fortifications built under Louis XIV, such as the Citadel of Château d'Oléron and Fort Louvois, as well as the famous Fort Boyard positioned on its sandbank offshore. The Chassiron Lighthouse, standing at forty-six meters high, marks the northern tip of the island and guides ships through the waters of the Pertuis d'Antioche. Beyond its defensive legacy, the island offers various natural areas where sandy beaches, pine forests, and salt marshes alternate. Saint-Trojan-les-Bains extends its wooded shoreline to the south, while Boyardville features a protected coast on its eastern side. Visitors also observe oyster farming along the La Baudissière channel and explore the colorful huts that house artist workshops at the port of Château d'Oléron. The Saltworks Museum traces the history of salt extraction, a resource that shaped the local economy for centuries.
