You can canoe on the Loire by renting boats in Saint-Aubin.
The managers of Les petits castors are two very nice young men, one French and one Dutch, who will be happy to help and advise you.
We have already done it several times and were totally enthusiastic. The landscape is beautiful and peaceful, you can stop from time to time on beautiful sandbanks, swim and have a picnic.
After choosing from different lengths of the route, the boats are collected in Saint Aubin and returned to the car at the agreed time of arrival.
