Wailua Falls, Kauai

Wailua Falls, Kauai:

Wailua Falls, just north of Lihue, is a step off the beaten path. Located at the south end of the Wailua River, it cascades into two streams, dropping 80-feet below. Some even say the distance is more accurately described as 200 feet.
Like other spectacular spots on Kauai used as film locations, Wailua Falls is most recognized in the opening credits of the long-running television show "Fantasy Island." Easily accessible, Wailua Falls can be seen from the roadside, so you can leave your hiking boots behind. To get there, head north from Lihue and follow Maalo Road in Hanamaulu. Travel uphill for about three miles. If you visit in the mornings, you may be treated to a rainbow, making for an amazing photo of Wailua Falls. This waterfall feeds into the Wailua River. 

There are many paths to the bottom of the falls, but it is difficult to use them because they can be muddy and slippery. The "trail" further from the parking lot is less steep than the closer one. Its about the ancient times in Hawaii when Hawaiian men used to jump from the top of this Falls to prove their manhood and male chauvinism. Some people still leap off the top of the falls, though it is dangerous and illegal. 
The pool made by this Falls is a great for swimming, but there are swift currents close to the waterfall.
