Wailuku River State Park is a 16-acre park located just outside of downtown Hilo and is home to several of the most striking waterfalls in the area. Set along the Wailuku River, the longest river in Hawaii, Wailuku River State Park features the 80-foot Rainbow Falls, which are named after the rainbows formed by the blend of mist and sunlight, and legends say that the cave beneath the waterfall was the home of Hina, an ancient Hawaiian goddess. The second set of famous falls in the park are the Boiling Pots on Pe'epe'e Falls Drive, which is a series of large pools connected by underground flow or cascades that look like boiling water as the water moves over the rocks. 2-198 Rainbow Drive, Hilo, HI 96720, Phone: (808) 587-0400,
