The Canal Saint Martin was opened in 1825 and was originally designed to bring drinking water to Paris and to provide an alternative to the Seine for industrial boat traffic. It has nine locks and two swing bridges and is open to navigation all year round. While commercial traffic on the Canal has decreased significantly, it has been more than offset by tourist boat cruises, and other leisure activities along the Canal. Canauxrama (see boat in picture) is one of two main companies that regularly run cruises on the Canal Saint Martin (the other is Paris Canal).
