Navigation
The Erdre winds north of Nantes — « la plus belle rivière de France » — before joining the Nantes-Brest canal. Fifteen kilometres through Natura 2000: herons, kingfishers, otters, over 200 bird species. Twenty-two châteaux line the banks.
Be among the first 8 to sail the Erdre aboard L'Hydronaute. This founder rate disappears at the official opening — and won't come back.
