A Unique Tropical Nature Preserve and Sanctuary

Onomea Falls Aloha and welcome to Onomea Bay and the Hawaii Tropical Botanical Garden! This "Garden in a Valley on the Ocean" is located off of Highway 19 on the lush Hamakua Coast's 4 Mile Scenic Drive, 8 1/2 miles north of Hilo on the Big Island of Hawaii. (click here for map, admissions and hours).

The Hawaii Tropical Botanical Garden is a museum of living plants that attracts photographers, gardeners, botanists, scientists, and nature lovers from around the world. The Garden's collection of tropical plants is international in scope. Over 2,000 species, representing more than 125 families and 750 genera, are found in this one-of-a-kind garden.

The 40-acre valley is a natural greenhouse, protected from buffeting tradewinds and blessed with fertile volcanic soil. Throughout this garden valley, nature trails meander through a true tropical rainforest, crossing bubbling streams, passing several beautiful waterfalls and the exciting ocean vistas along the rugged Pacific coast.

The Hawaii Tropical Botanical Garden is a 501(c)(3) Scientific and Educational non-profit, whose mission is to serve as a nature preserve and sanctuary, a living seed bank, and a study center for trees and plants of the tropical world. The Garden is dedicated to the collection and display of the world's tropical plants,and to the education of both children and adults about the plight of the world's rainforests. At a time when rainforest plants are disappearing at an alarming rate, the Garden is working to preserve as many species as possible for the benefit of future generations.

If you are visiting Hawaii on a cruise ship and would like to visit the Garden, we can pick you up at the pier! See your shore excursion staff or visit Tour Dispatch for more information.
