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.

A truly beautiful section of the route. It might be problematic on a road bike, though. It's fine on a gravel bike. Sometimes, though, you have to push your bike for a few meters if the sand is too deep.

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.
