Canal Saint-Martin towpath
A Napoleon-era canal of 1825 climbing through nine locks and arched iron footbridges, where you can stand on a passerelle and watch boats rise and fall between basins. Tree-lined cobbled quais run either side before the water vanishes underground.
Walk the Quai de Valmy stretch between Rue des Récollets and Rue de la Grange-aux-Belles for the best run of locks. Sundays both quais go car-free.
