SELF DRIVE RIVER BOAT RENTALS FROM Saint-Martin/Oust


 

Saint Martin sur Oust is a small rural village, with little trade. Remember to visit Castellan Castle before going on a cruise. This base is the starting point for one-way river cruises on the Nantes-Brest Canal / Vilaine to Melesse.

The locks are electric and manned by lock keepers. They are always open.

In Britanny, river cruises are mainly done on canals (except between Redon and Rennes). Easy on the whole, little current, few dangers - this region is perfectly suited for a first river cruise experience,

Whether on the Nantes-Brest Canal or on the Vilaine River, mooring is only permitted in designated places and not along the banks.
