We might be going camping up there next weekend. It's been 10+ years since I've been & DH has never been. I remember there being a Ripley's museum & DH wants to go see all the Tesla stuff since he's a computer & electrical engineering prof. And the casinos. Other non-waterfall things to do? The cheaper the better (or free). Thanks.
There is Botanical garden/butterfly conservatory I believe there is an Aquarium (I didn't go but I remember seeing signs for it) Niagra on the Lakes has a vineyard tour/wine tasting.
