Wailuku River State Park boasts two main attractions: Boiling Pots and Rainbow Falls.
Boiling Pots is a succession of big pools connected by underground flow or cascades and whose waters roll and bubble making it appear like it’s boiling. The columns that line the pools were formed by the slow cooling of lava.
The 80 foot Rainbow Falls is renowned for the rainbow formed from the rainbow that can be seen at around 10 AM on sunny days due to the mist of the waterfall. Legends say that the cave beneath the waterfall was the home of Hina, an ancient Hawaiian goddess.
