The trail is mostly in woodland. After a first uphill climb you then head down into a dale where you will certainly enjoy yourself on some very impressive, technical sections. Then you will discover the Bois de Sizay, as you go up its narrow paths and wide tracks. The descent towards Saint Donat is on a wide, however, rough track . Be careful not to lose control here.
