I have to give my honest opinion and it will probably suprise some people but my favorite side of the Falls was the US side. I felt that the Canadian side was way too commercialized, in fact it was a ZOO! I found it very refreshing and alot more relaxing on the US side. With the addition of the observation tower, you can get a good view of both falls, the Maid of of Mist was the same on both sides and the Cave of the Winds was so much better than Journey Behind the Falls on the Canadian side. Also we took the jet boat tour (highly reccommended) which can be done on either side US or Canada. If I had it all over to do again, I would have stayed on the US side and walked over to Canada for a day, by car it took us 2 hours to go over the Rainbow Bridge into Canada and an hour to get back to the US the next day.
