We purchased a Passport to the Falls for $24.95 ($17.95 for children), payable by credit card, which is a combo ticket for the major attractions. We opted to stay on the American side for our Falls tours, and I think the passport comes out a little cheaper than on the Canadian side (and the experience is bound to be very similar). We didn’t go to the Aquarium, the Discovery Center, or the film, but those were included in the ticket. We started with the famous Maid of the Mist boat tour (and were glad we did this in the morning as throughout the day the boats appeared to be much more crowded). Included in your ticket is a rain poncho, but despite this you will get wet. The half hour boat ride takes you right close to the Falls, and the mist sprays all around. We were there on a cloudy day and therefore did not witness a rainbow. If you do the Maid of the Mist first, we suggest hanging onto your poncho for Cave of the Winds because it’s a little longer/better.
