Rainbow Falls (Waianuenue)
An 80-foot waterfall in the heart of Hilo that drops into a circular pool surrounded by a cave and tropical vegetation. The falls are visible from a paved overlook just steps from the parking lot making it one of the easiest waterfall viewpoints in Hawaii. On sunny mornings, rainbows form in the mist at the base of the falls, which is how it got its name. A short trail leads to the top of the falls through a grove of enormous banyan trees. The whole visit takes 15 to 30 minutes. A perfect quick stop in Hilo.
