If going to Montreal in a motorhome, this is a hidden gem. OK, no services except electricity (my rate was with no electric). But this is right on the river across from Montreal and 5 minutes from the metro, 10 by bike, 15 on foot. Plenty of space and the price is right. If you prefer, the water taxi departs every couple of hours from this same spot, which is part of the marina. A manned gate for security. Right on the Vert #1 bike path, across from the Olympic park. If you just want easy and close access to the city, this is a great choice. We camped here in a Motorhome.
Sogerive is a municipal corporation managing a marina and the rv park next to Jacques-Cartier bridge on the St-Lawrence river. It is the closest park to access Downtown Montreal. Fireworks every Saturday nites off the bridge, nice views from your site. There is a dump station. Adresse is 101 Chemin de la rive, Longueuil, Québec,J4H 4C9 Would highly recommend for 3-4 nites for city viewing-tours etc... Enjoy! We camped here in a Fifth Wheel.
