4 Best Botanical Gardens on Oahu Hawaii

Given the Island’s naturally beautiful foliage, visiting the botanical gardens on Oahu might seem a bit redundant -- sort of like going to the zoo in Australia.

Like, just walk outside…

But we can assure you that Hawaii’s botanical gardens are absolutely worth the trip. In this article, we’ll give you everything you need to know before you tour the botanical gardens on Oahu!

1. The University of Hawaii at Manoa Botanical Gardens

Much of the University of Hawaii at Manoa’s campus is actually considered a botanical garden. The university’s botanical gardens even have an official tour route!

Anyone who has walked through the university’s campus probably isn’t too surprised to learn that the school is basically one giant botanical garden. In fact, each dot on this map represents a plant you may be interested in seeing!

We’d particularly recommend checking out the Japanese garden just off of East-West street below Jefferson Hall. The area is absolutely beautiful and has plants you can’t see anywhere else on the island.

The university’s Japanese garden was designed by the famous architect Kenzo Ogata and has a coral shower tree planted by the current emperor of Japan when he was just a prince!

The University of Oahu also operates the Lyon Arboretum, which has many individual gardens inside. It's located in Manoa, not too far from campus, and is a stop on Shaka Guide's Honolulu Backyard Rainforest Tour! We recommend turning on the tour to check it out along with the beautiful overlooks and waterfall this area has to offer.

Ease of Access: Extremely easy and accessible for all
Location/Address: The entire University of Hawaii at Manoa campus. Check signs carefully to know if parking passes are required in a specific lot.
Best Times To Visit: Spring for the blooms
Cost: No cost depending on where you park. If you drive past a certain point on East-West street, there’s a campus toll booth.
How long will you spend there: You can do all of the gardens in two hours, according to the official tour.

2. Waimea Valley Botanical Garden

The Waimea Valley Botanical Garden is home to 36 botanical gardens and collections. Each one has its own theme such as the ethnobotany collection which features plants used in Hawaiian culture as food, medicine, tools, and even weapons.

There is so much to see here.

Across these 36 gardens and collections, there are over 5000 different species of plants. Many of these plants are native to Hawaii and endangered. A select few species are found nowhere else in the world besides the Waimea Valley thanks to the staff’s commitment to acquiring and preserving endangered species.

In addition to the gardens, your admission includes access to all Waimea Valley has to offer -- this means you can take the short hike to a waterfall where you can swim beneath the falls.

Some of Foster Garden’s plants have been there since the 1850's when Dr. William Hillebrand first started the garden and thus the entire Honolulu Botanical Gardens system. Foster Garden now includes a conservatory, an outdoor butterfly garden, a palm garden, and a prehistoric Glen Cycad Collection.
