Are there good walks taking in megalithic sites?
Forget Carnac, if you want to avoid crowds. Just as impressive and far more accessible are the alignments of St Just in Ille-et-Vilaine (circular walk of 13 or 10kms here given in Walking Brittany by Judy Smith or leaflet from the Mairie). If you have visited the Carnac site, drive westwards a few kilometres towards Erdeven and you will find yourself among the alignments of Kerzerho. A circular walk of 8kms here, taking in many Neolithic remains, features in the Red Dog Book guide Central Brittany: Coast to Coast. If you want to make a pagan pilgrimage to the largest standing stone (still upright) in France, there is a marked circuit near St-Renan (north of Brest). Many of the other lonely menhirs of western Brittany can be seen on routes in Walking and other Activites in Finistere (see books).
