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

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

The two comic book heroes Asterix and Obelix, who are very popular not only in France, discover Brittany and the huge stone rows from ancient times that can be found there on their very own "Tour de France" (under the title "Le Tour de Gaule", volume 5 of the French edition, but volume 6 in the German edition). The explanation given to the two travellers for the origin of the megalithic culture is, however, too simple: people say that the soil is so bad that only stones grow there; this can be read in the comic.

The Alignement de Kermario may not have the most megaliths, but it does have the largest and most impressive ones. All megalithic fields are fenced off, but a beautifully laid out and well-signposted circular path opens up and connects the megalithic fields and allows you to see the stone witnesses of history from the path. Don't forget that it doesn't cost a cent to walk the paths.

It is a strip of land, about twenty meters wide, which connects the Quiberon peninsula to the continent. On these few meters a road, a railway line and the cycle path coexist. You can also enjoy the beaches that border the isthmus.

Impressive isthmus between the mainland and the peninsula. Not much more than a road and a single-track railway line fit on it.
