2 Best Sights in Side Trips from Toronto, Ontario

This 30- to 45-minute tour starts with an elevator ride down to an observation deck that provides an eye-level view of the Canadian Horseshoe Falls and the Niagara River. From there a walk through tunnels cut into the rock takes you behind thunderous waterfalls, and you can glimpse the back side of the crashing water through two portals cut in the rock face.

Rising 775 feet above the falls, this is the best view of the great Niagara Gorge and the entire city. The indoor-outdoor observation deck has visibility up to 130 km (80 miles) on a clear day. Other reasons to visit include amusements for children, a buffet restaurant, a revolving dining room, and a 3-D theater that lets you experience the falls up close. Admission is free if you're enjoying a meal in the dining room.
