Rainbow (Waiānuenue) Falls is a large waterfall, measuring 80 ft (24 m) tall and almost 100 ft (30 m) in diameter. It is free to enter and see the falls because this area is part of the Hawai'i State Parks. There is no fee to see the falls. Rainbow Falls gets its name from the rainbows that show around the falls, created by the mist from the falls and the sunshine at 10:00 a.m.

The Naha Stone was a sacred stone to test a member of a particular bloodline for leadership. Whoever could move the stone possessed the 'mana' or spiritual power to rule.

The 80-foot Rainbow Falls is a beautiful sight to see. While the falls itself is not safe for swimming, the pools above the falls are safe given the weather is good. Legends say that the cave beneath the waterfall was the home of Hina, mother of the demigod Maui.

A major draw at Coconut Island is the opportunity to visit its 20-foot diving tower. If you decide to take the plunge, exercise caution, especially during peak usage, as the platform can become slippery.
