Wild Rapids Waterslide Park was located on the shores of Sylvan Lake in the resort town of Sylvan Lake, Alberta, Canada. Wild Rapids opened to the public in 1982, and it was Alberta's second-largest water park after the World Waterpark in West Edmonton Mall. Wild Rapids Waterslide was one of five waterslide parks in Alberta, and the last outdoor water park to operate until it closed in 2016. The park contained 12 slides, many small pools, three hot tubs, and a children's water playground. The park closed at the end of the 2016 season, after operating for 34 years. The park was located near Red Deer, between Edmonton and Calgary, along Alberta Highway 11A. Wild Rapids was the largest water park of its kind in western Canada.
