Take a Ferry to the South Shore
As montrealers we have lots of opportunity to ride along side the river or over the top with bridges. How about getting down to water level, and take a ferry!
There are at least two ferry boats services between Montreal and the south shore.
Montreal's Old Port (Vieux Port) to Longueuil
Hourly service from 10:30 am to 10:30 pm, approx, please check the link for the exact schedule.
Departures from Longueuil take place at the Port de plaisance de Longueuil, close to the Parc Marie-Victorin. Access for pedestrians and bickers by the foot-bridge and Chemin de la Rive. Access for cars by the Parc Marie-Victorin (free parking). Departures from the piers of the Old Port of Montreal take place at the Jacques-Cartier Pier, in front of the Place Jacques-Cartier in the Old Port of Montreal.

Cost $6.00 adults
West: Cross St Laurence either of two places in Valleyfield, return by Vaudreuil & Ste-Anne-de-Bellevue and lakeshore (long ride, great weekend day ride).
East don't take pont mercier (very scary/dangerous), instead make a long ride and cross back to Montreal Island at Saint Catherine & seaway bike path & estacade, or via Parc Drapeau (saint Lambert Locks) or the "bridge with a view" pont Jacques Cartier
South: Riding the Ghateauguay valley. Ride upriver to old wooden covered bridge at Powerscourt, near the US border. (from here return east to Rockburn and go north to Dewittville where you rejoin the chateauguay river.) This is very scenic once you are past Mercier. This is a very beautiful area of Quebec. Tip: Take the north side of river to Ormstown, south side to Huntingdon. Shorter option is to go turn at dewittville to Rockburn to T intersection where you join this is road from powerscourt (or return this way)
