Whirlpool Rapids Gorge, New York
During the 1970s, the American side of Niagara Falls was becoming commercialized with lots of tourists coming to paddle through the rough waters. Due to its class five rapids, paddling became a deathtrap for many visitors. Therefore the site closed and has remained that way for decades.
Upper Section of the Futaleufu River, Chile
When visiting Chile, we recommend giving this site a skip. The “Upper Section” of the Futaleufú River is a 14-mile-long stretch of dangerous rapids. Not only does it take a professional to tackle these raging water, but it also takes unflinching focus to be able to navigate as the waters change course on a whim.
