A lovely walk along the coastal path, you'll walk in the shade of trees and vegetation reminiscent of the Mediterranean. You'll discover magnificent views of the Gulf of Morbihan and the Ile aux Moines in the background. When the tide is low, oyster and mussel beds, as well as a boat cemetery, are revealed along the way. Be careful, the island is only accessible at low tide!

This memorial is extremely interesting because it depicts the blue uniform worn by French infantrymen during World War I. The introduction of the blue-grey uniform (known as "horizon blue" because it was believed to prevent soldiers from standing out against the skyline) had been approved by the French Chamber of Deputies on July 10, 1914, but a new issue was not possible until the outbreak of war a few weeks later.

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.

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.
