"To access the 282-foot-tall Niagara Falls Observation Tower, head to Prospect Point in Niagara Falls State Park on the U.S. side. Tower admission is $1.25 per person, and you can see all three falls from the observation deck. If you're feeling adventurous, take the elevator to the bottom of the gorge, then hike up the stairs to the Crow's Nest viewpoint for an up-close look at American Falls." - Travel + Leisure Editors
