Onomea Falls is located inside of the Hawaii Tropical Botanical Garden (Admission required). Onomea Falls is set amidst the natural forest of palms and ferns and is located along the pathway inside the garden.
Exotic mosses grow on the surrounding rocks, trees and the small bridge in front of the falls allows for an even better view of the falls and stream, plus it makes for a great photo opportunity. According to the HTBG website, the falls was discovered far by Dan Lutkenhouse, years after work on the lower Hawaii Tropical Botanical Garden began. One day he decided to hack his way through the jungle alongside the stream, and much to his delight he found the magnificent waterfall.
