When the wind blows from the east, kitesurfers flock here. Beautiful views of Carnac.

The dolmen stands in the middle of the village, close to a house. It once had a long passage and measured 27 meters in length. The cover plate weighs approximately 40 tons. For a long time, it served as a barn.

Unpaved bike path. Fine sand on a firm surface. Easily accessible by road bike. However, it can be quite dusty when dry.

We recommend taking the short ferry crossing. This saves you the detour over the bridge to the north. This is a good option if there aren't too many cyclists waiting. The ferry only takes three bikes at a time. Payment is made on board, in cash or by debit card.

The Quiberon Peninsula loop from Erdeven (50 km) is a must-do. More than 40 km of cycle path. Magnificent scenery.
