If you're ever in Montreal, specially during the summer, have a picnic, or go for a stroll in Rene Levesque Park. There's a bike and roller blade rental shop at the entrance to the Park. The marina is usually full with all sizes of boats, yachts. You may also board a cruise boat that'll take you for a short tour along the St. Lawrence river - dinner is available. Lots of fine restaurants (reasonably priced too) along St. Joseph's Blvd (parallel to the bike path).
