Carnac is located not far from the Gulf of Morbihan, the city is known worldwide for its alignments of menhirs.
The walk presented is quite short, it can be done in one hour if you go fast. Then it depends if you want to reach the other alignments by car or on foot. To see all the sites on foot it is necessary to count 3-4 hours. As there are no explanations on the site, it is better to take a guided tour (13 €). The alignments at Carnac are made up of 3000 menhirs erected between 5000 and 2000 BC. They form a 4 kilometers long set. Explanations have been given but nobody really knows why men have aligned these blocks of stone. The mystery remains.
