Carnac is famous as the site of more than 3,000 prehistoric standing stones. The stones were hewn from local rock and erected by the pre-Celtic people of Brittany. Local tradition claims that the reason they stand in such perfectly straight lines is that they are a Roman legion turned to stone by Merlin (Brittany has its own local versions of the Arthurian cycle).
The Carnac stones were erected during the Neolithic period which lasted from around 4500 BC until 2000 BC. The precise date of the stones is difficult to ascertain as little dateable material has been found beneath them, but c.3300 BC is commonly attributed to the site’s main phase of activity. One interpretation of the site is that successive generations visited the site to erect a stone in honour of their ancestors.
There are a number of camping grounds in the woods around Carnac, some clustered around various lakes such as the Etang du moulin du lac which is immediately to the west of the river Crac’h.
For windsurfers, the Saint-Colomban beach located in Carnac-plage, is one of the best spot for windsurf in France.
