Wailua Falls is a waterfall on the island of Kauai, part of the US state of Hawaii.

The 173 foot (52.7 m) [1] falls are located on the South Fork Wailua River near Lihue.

The waterfall is prominently featured on the opening credits of the television series Fantasy Island.

In ancient times, Hawaiian men would jump from the top of the falls to prove their manhood.

In 2016, a man jumped from the falls and was knocked unconscious but narrowly avoided death when someone swam out into the pool to save him.
