On the 11th of May, as we reached the top pound of the Canal de Briare, Wanderlust moved from the Seine River drainage to the Loire River drainage. From the beginning in Montargis, the Canal de Briare climbs 279 feet to its summit. Much of the climb occurs in the closely spaced locks that are clustered near the summit. On foot, climbing 279 feet may not seem like much. In a 40 tonne boat, climbing 279 is an amazing feat of engineering.
(Wanderlust passed through 12 locks in 8 kilometers before stopping for the night in Ouzouer-sur-Trézée.)
