Hiilawe Falls (or Hi’ilawe Falls) was once one of the mightiest waterfalls in all the islands of Hawai’i with a cumulative drop of 1450ft in Waipi’o Valley.

Waiulili Falls is an ocean-bound waterfall accessible via the sacred Waipi’o Valley (another being Kaluahine Falls) reached by a sketchy coastal scramble.
