The Uma uma waterfalls are situated in the World Botanical Gardens, about 17 miles north of Hilo. It’s a three-tiered waterfall where each tier of the waterfall falls into a tranquil pool before cascading on to the next tier.
There is a $6 entrance fee (Kama’aina, $13 for visitors) which isn’t bad, and for that you get the waterfalls, a walk through rain-forest and the gardens. The jewel in the crown is clearly the waterfalls – if you want rain forest and exotic floral variety, I would recommend the Hawaii Tropical Botanical Garden in Onomea Bay (sorry, don’t know the prices).
A selection of some other pictures that I took are below.
