"Terrific tour, and seeing the falls from a boat is the best way to see them in their entirety. Our guide was Mark the Candian. He was great---very informative and knowledgable of the area. He also told us about people who have challenged the falls, as well as some of the past and present uses of local buildings. You definitely want a camera. Best to wear footwear that can get wet, and if visiting near the end of the season, have a warm jacket with a hood or a heavy hoodie. Taking the Maid of the Mist is a must to be able to get a bird's-eye view of the powerful Niagara Falls. I was there late in the season and had no trouble with tour reservation. Thank you Mark."
