A pretty stage on a designated track of La Vélodyssée through a sinuous valley of the Oust with the foothills of the Landes and Lanvaux as a backdrop. After passing the confluence with the Claie, St Congard and the Guélin Lock provide very welcome breaks.
Easy going surface on this section with designated lanes. Take care when crossing the Roc-St-André Bridge; follow the signs to change banks. Take care at the section under the bridge at Malestroit. Very easy-going surface between the Beaumont Lock and St Congard; uneven ground coming into Peillac.
The regional cycle-path n°3 St-Malo > Rhuys crosses the Canal three times between Guillac and Malestroit.
Small, quiet roads to get to St-Laurent-sur-Oust.
