About 15 years ago we stayed at the KOA on Canadian side on Lundy's Lane. It was a great park, stuff for kids to do, and the city bus stopped multiple times a day at the entrance - it brings you right to Niagara Falls. This was a long time ago, so I don't know how things are today.
We ate at the Skylon tower restaurant over looking the falls - very cool restaurant and we had a great time. We did the buffet, and I am sure they did not make any profit that day! lol!
Most nights the falls are lit up with colored spot lights. There is a lot to do on the Canadian side, it is very built up and touristy.
