Cliff jumping is a dangerous but exhilarating experience that people love doing all over the world, but when done wrong, it can paralyze or even kill someone. One of Arizona’s most dangerous waterfalls known for cliff jumping is Havasu Falls. It’s highly recommended that people do not jump because of the height. But extreme athletes don’t take no for an answer. Beware of the height, rocks and water levels if attempting to jump, which only experienced jumpers attempt.
