Take an elevator to the bottom of the Niagara Gorge and enjoy a walk along the boardwalk adjacent to the mighty rapids of the Niagara River. The rapids is 305 meters (1,000 feet) and stairs lead to two observation areas at the edge of the River. The water travels at different speeds along the length of the Niagara River. South of the Falls where the river is wide and slow, the maximum speed is about 40 km/h. Near the brink of the Falls, a speed of 109 km/h has been recorded. As the water travels through the Whirlpool Rapids at White Water Walk, it is traveling at about 48km/hr or 30mph, creating the Whirlpool Rapids – “Class 6 white-water rapids”. Viewing area & Walkway at the “Great Gorge Adventure”. Located 1/4 mile (402m) North of the Whirlpool Bridge on River Road
