Rent bikes at Ca Roule Montreal (27 rue de la Commune Est), and bike along the Lachine Canal, past the old mills, warehouses and grain elevators that line the waterway. Along the route, you’ll spot boats waiting for the water to rise at locks so they can move onward. A half hour into the jaunt, you’ll cross a small bridge, lock up the bikes and head into the Marche Atwater. Get ready for a feast of Quebecois cheeses, fruits, breads and dessert. That should give you more than sufficient energy to bike back.
