My wife and I went to Niagra two years ago and parked in the casino lot on the US side for two nights and just dry camped. We do not tow a car so that was close enough to walk or bike to everything we wanted to see. We did not go into Canada given the amount of contraband on the bus. That said, the US side was very depressed while the Canadian side looked like Disneyworld from what we could see.
