Wailua Falls is an 80-foot waterfall located in Kauai, Hawaii that feeds into the Wailua River. There is a path to the bottom of the falls, but it is muddy, slippery and dangerous. Some hikers have strung ropes along the path, but officials come by every so often and cut them. In ancient times, Hawaiian men would jump from the top of the falls to prove their manhood. There is another waterfall nearby named 'Opaeka'a Falls.
