With enticing beaches and a pretty town centre, Carnac would be a popular tourist town even without its collection of magnificent megalithic sites, but when these are thrown into the mix you end up with a place that is unmissable on any ramble through Brittany. Predating Stonehenge by around 100 years, Carnac (Garnag in Breton) also tops it with the sheer number of ancient sites found in the vicinity, making this the world's greatest concentration of megalithic sites. There are no fewer than 3000 of these upright stones, most around thigh-high, erected between 5000 and 3500 BC.
Carnac, some 32km west of Vannes, comprises the old stone village Carnac-Ville and the seaside resort of Carnac-Plage, 1.5km south, bordered by the 2km-long sandy beach. Its megaliths stretch 13km north from Carnac-Ville and east as far as the village of Locmariaquer.
