If you think Niagara Falls is impressive from the front, try viewing it from the back! This tour takes visitors in an elevator to the base of the waterfall and lets them see, from behind, the sheer magnitude of the water as it's forced over the cliffs above. An observation platform provides views from the side, while tunnels and portals cut into the rock lets folks experience the rush of water from within the falls. Tours are self-guided, rain gear is included and a gift shop is available after you've made your way through.
