Walking
France is literally covered in sentiers, tracks for farmers. Unlike in Britain where these tracks are owned by the local farmer, but over which the public sometimes has right of way, in France the tracks are owned by the commune and have the same access rights as tarmac roads.
The tracks are clearly marked on the larger-scale IGN series of maps and are usually very easy to follow, as they're still in regular use by farmers and, occasionally walkers. Every now and again one has been ploughed up (usually illegally) and disappeared. Often, an alternative route is just a few hundred yards away.
There also a myriad of waymarked routes. The commune of Cormolain has a couple of short hour-long strolls around the lanes, but there are longer walks in forests, along the beaches or just to the south, in Swiss Normandy (Suisse Normande), where many of the walks lead you to the spectacular views, although to call it 'Swiss' is a gross exaggeration!
For the more adventurous it is easy to walk a section of one of France's famous Grand Randonnées, as Swiss Normandy has one running through its most spectacular sections, less than an hour to the south.
