1. Wailua Falls
One of the best waterfalls in Kauai, Wailua Falls is situated north of Lihue at the end of the Wailua River. This spectacular two-tiered waterfall is 80 feet tall and famous for being a filming location for the 1970s TV series, Fantasy Island.
This picturesque fall in Kauai is easily accessible and can be viewed from the nearby car park. If you want an impressive view of the fall, it is recommended to visit the site after rainfalls or in the early morning to catch a glimpse of a rainbow when the light is just right.
As the base of the fall is steep, wet and slippery, it is wise not to hike down to the base of the Wailua Falls.
