We are in the Marias district of Paris and would like to do a hop on hop off bus tour. Where do we go to get on the bus from here? We are near the archives.
Google "hop on hop off bus paris" and a web site will come up. You can download the route map for the different tours. There seems to be a stop for the Marais on rue St. Antoine. It's probably near Eglise St. Paul.
