Impressive dimensions. It is hidden away in a dead end street and absolutely worth seeing. In the immediate vicinity there is another dolmen, a pretty old mill and great little houses with thatched roofs.

Bike barge only really runs on weekends in June. Don’t get caught out like I did and have to ride all the way round/through the salt marshes in the evening wind and rain.

Worth seeing dolmen. Just follow the path from the road 150m. After another 50m there is another "fallen" dolmen on the left side.

Flat, smooth rocks and a playground made of boulders as big as houses. This point is a treasure and worth observing while passing.

Before reaching the tip of Pen Bé which is at sea level, you can take advantage of this much higher point of view and the cliffs which offer you beautiful views of the surrounding coastline.
