Fort de Bertheaume
A Vauban fortress on a rocky islet in the sea, connected to the mainland by a drawbridge. In summer, you can walk high ropes and ride a zip line over the water.
The fort is located in Plougonvelin. Vauban reinforced it in the late 17th century to guard the Brest Strait. The islet offers climbing, high ropes and zip-line adventure activities, and there are sound-and-light shows on summer evenings. Even without entering the fort, the bay and coastal paths beside it offer excellent scenery. It is about 5 kilometres from Pointe Saint-Mathieu.
Opening hours
Summer approx. 10:00–19:00
