Aquazilla, our favourite aquatic playground, is a giant, inflatable obstacle course anchored just off Jean-Doré's sandy beach in Parc Jean-Drapeau. Bonus: The 30-by-35 metre structure is just a 15 minute drive (or metro ride) from downtown Montreal
UPDATE, Summer 2022: Montreal is a playground for kids of all ages. The city is full of attractions for young children (and the young at heart), and excellent places to eat that are easy on the budget. Every borough has its own family-forward fun—not to mention some awesome Montreal parks and spectacular urban beaches—and each is easy to get to via public transportation (five-year-olds and under ride for free!). Coolest ice cream spots across the city included.
