A Unique Tropical Nature Preserve and Sanctuary
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. (scroll down 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 for more information.
The Garden is open from 9am to 5pm everyday, except Thanksgiving, Christmas and New Year's Day, with Garden admissions ending at 4pm. This self-guided tour takes an average of about an hour and a half. The walking distance is just over a mile, round trip.
Admission for a day is $20 for adults, children ages 6 - 16 are $5. Children under 6 are free.

Golf Cart Assistance
Visitors walk the 500 foot dramatic, beautifully landscaped boardwalk down into the Garden on the ocean. This boardwalk alone is a photographer's paradise that should not be missed.
The boardwalk is not wheelchair accessible. The Garden provides golf carts to transport wheelchair-bound visitors with their companion and their wheelchairs up and down the boardwalk. Once you've exited the boardwalk, you may use your wheelchair through most of the Garden. Only non-electric wheelchairs are permitted entry into the Garden.
For a $5 per person fee, Golf Cart assistance can be provided to those visitors that are not wheelchair-bound but otherwise physically limited.
To preserve the serenity and non-pollution of this beautiful garden we discourage the use of golf carts on the boardwalk unless absolutely necessary.
