[2][3] La Coubre is 64 metres (210 ft) high and is the highest in the department.

The lighthouse is located in the "Pointe of La Coubre", 15 km from Royan and at the north of the Gironde Estuary, close to the Bonne Anse Bay.

The "Pointe of La Coubre" and the sandbank separate the calm water of the Gironde Estuary, and to the north, the Atlantic Ocean.

[citation needed] After climbing the 300 steps among the opaline on the walls, visitors can see the Wild Coast (Côte Sauvage), the beaches, the La Coubre forest, the Gironde Estuary and the Cordouan Lighthouse (the oldest in France).

In another room, marine objects are shown, a device measuring the fog, old lenses and other mechanisms.
