Several dangerous crossings on this section: RD 32, RD 125 and RD 768. Very easy going road surface and gentle downhill gradient between St-Gonnery et Rohan. From Rohan to Josselin the itinerary is on dedicated lanes with an easy going surface. Short cycle down a little lane as you get to the hamlet Le Val just before Griffet Lock.
Take care when changing sides by the RD 764 to Bocneuf-la-Rivière.
On small hilly lanes towards St-Gérand, St-Gonnery and Gueltas.
On a level with the Timadeuc Lock area, there is a signposted connection to Timadeuc Abbey.There is a small beach near the Abbey.
