Rainbow Falls

Rainbow Falls is one of the Big Island's most breathtaking natural spectacles, where the Wailuku River cascades 80 feet over a volcanic lava rock ledge into a serene, emerald pool below. The falls earned their enchanting name from the iridescent rainbows that appear in the mist on sunny mornings, typically between 9–10 AM — a truly magical sight that draws visitors from around the world. According to Hawaiian legend, the cave beneath the falls was home to Hina, the mother of the demigod Maui, making this site not only visually stunning but deeply rooted in Hawaiian culture and mythology. Guests staying at Ala Kai will find Rainbow Falls to be an easy and rewarding day trip, just a short drive away near Hilo. A well-maintained paved path leads directly to a lookout platform offering dramatic views of the falls, making it accessible for visitors of all ages and mobility levels. For the more adventurous, a short trail to the left winds up through a grove of massive banyan trees to a higher vantage point that rewards with a panoramic view stretching across the falls and surrounding rainforest canopy. The best time to visit is early morning on a sunny day to catch the rainbow mist in full glory — bring your camera! The site is free to enter and rarely crowded before 9 AM. Wear comfortable shoes as paths can be slippery after rain, and bring insect repellent if you plan to explore the upper trail. Parking is available on-site, and the entire visit is wonderfully low-key — a perfect, no-fuss way to experience the natural wonder of the Big Island.
