Oh, Montreal really has a lot to offer in the summer! If you're looking for outdoor activities, be sure to try a picnic in one of our parks. For example, Mont-Royal is a great place for a picnic, and you can also go biking, boating, and enjoying nature. I also recommend visiting festivals - there are over 90 of them! There's an international jazz festival, Comiccon, and even a sci-fi film festival. Don't forget about food tours, Montreal is famous for its cuisine, especially pudding and smoked meats. And if you want to learn more about culture and science, visiting museums with the "Space for Life Passport" would be a great idea!
