The arid, volcanic landscape of the west side of the Big Island exists in contrast to the lush, green eastern side, where waterfalls plunge off sea cliffs and flow through lush valleys. See famous waterfalls such as stunning Rainbow Falls, majestic Akaka, or towering Hiilawe. These waterfall tours are the best way for you to see the beauty of the Hilo side, whether you're exploring Waipio Valley, doing a nature walk, or flying to a secluded pool via helicopter.
