How to Get There

The park is an easy jaunt from Hilo by car or bicycle. Take Waianuenue Avenue two miles from downtown and turn on Rainbow Drive to find the parking lot for Rainbow Falls. To reach the Boiling Pots and Pe’epe’e Falls overlook continue 1.5 miles (2.4 kilometers) past the turnoff for Rainbow Falls. If you are visiting from a different part of the island, consider a tour which includes the falls alongside other Keaukaha Coast attractions.

When to Get There

The park is open daily from dawn to dusk. The best time to see rainbows at the falls is around 10am on a sunny day. To see the falls and boiling pots at their most dramatic, visit after a heavy rain. If water levels are low you will not see the boiling effect at the Boiling Pots. To avoid crowds, visit before the tour buses that typically arrive between 10am and 2pm.

Wildcard

The Creation of the Boiling Pots The Boiling Pots were formed by the combined effects of water and lava at the point where the Mauna Loa and Mauna Kea volcanoes met and the Wailuku River coursed through, creating the gorge. When the lava cooled in the river bed it formed the deep vertical columns that are now the Boiling Pots. When the water is not high enough to create the boiling action the section of the river appears as a series of terraced pools.
