I had my second trip to Montreal and my second jet boat tour with my family. Both times it was the highlight of the trip. Think twice however about sitting in the front row. Every wave came crashing into your face. My wife thought she injured her neck, and everyone else ended up with lots of water up their nose. A couple of answers to questions we had before we went:
They have changing rooms and an area to keep valuables. They offer you pullovers to keep warm, water shoes and ponchos that are wind breakers. Nothing will keep you from getting wet. On the boat, our row had rubber bags that you could put your glasses in right before you go down the rapids.
