The Alignements de Kermario sit approximately at the centre of the Carnac alignments, and are the most visually impressive section of the complex. This is where many people begin their visit, but my favoured approach would be from the Alignements de Kerlescan at the north eastern end. If, however, you wish to jump in at the deep end, the Alignements de Kermario are located next to plenty of parking facilities, and benefit from the provision of a small crêperie and souvenir shop.

Carnac can be slightly overwhelming, and it's a good idea to do some research before visiting, as there's a lot here that would be easy to miss. It also helps to have a mental image of the lay-out of the site, as this helps put things in perspective on the ground.

Access to the alignments at Carnac is now prevented by a low wire fence, due to excessive erosion caused by large numbers of tourists. However, access is still allowed out of season, but specific dates should be checked before travel.
