Botanical Gardens on the Big Island

You are here: Home >> Activities >> Botanical Gardens

The northeastern side of the Big Island is lush and tropical thanks to a combination of the high volcanoes, constant trade winds, and tropical temperatures. The Hilo and Hamakua coasts are filled with rainforest, waterfalls, and tropical flowers and these natural treasures can be most easily seen in one of the botanical gardens on the Big Island.

Botanical gardens, gardens, and arboretums. What is the difference?

The line between a botanical garden and a ‘normal’ garden or a park is not very clear. For the use in our guide we use the definition proposed by Wyse Jackson (1999):

Botanic gardens are institutions holding documented collections of living plants for the purposes of scientific research, conservation, display, and education.

We are quite relaxed with this definition, and all but two of the gardens in our list make it to the ‘botanical garden’ side.

The only two that don’t make it are the Akatsuka Orchid gardens, whose main purpose is selling orchids, and the Liliu’okalani Gardens, which is a Japanese garden inside a public park. Both these places are still very pretty to explore, and that is why we keep them on the list.

An arboretum, finally, is a botanical garden but for woody plants (trees). Basically, it is a collection of trees that are special for one reason or another.

List of Botanical Gardens on the Big Island + map

There are botanical gardens spread all over the Big Island, and you will very likely pass close by a couple of them during your travels on the island.

Visiting one during your stay then only takes some smart planning using the following map of botanical gardens on the Big Island.

On the following map, botanical gardens are marked as a pink flower, normals gardens are marked with a green flower, and arboretums are marked with a dark green palm tree.

Each of the gardens is described in more detail below the map.

Hawaii tropical botanical gardens (Hilo/Hamakua)

This is hands-down our favorite botanical garden on the Big Island. This is why we also have listed it as one of our 5 favorite short hikes on the Big Island. If you don’t like walking that much you can also see it as part of one of our favorite scenic drives.

The HTBG features over 2,000 species of tropical plants all inside a 40-acre valley. 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.

Botanical Gardens at the University of Hawaii (Hilo)

The UH Hilo Botanical Gardens consist of three separate areas that feature cycads, bromeliads, and palms. Currently, they include one of the largest collections of cycads in Hawai’i with over 100 species. One section of the garden has over 40 species of Zamia from Mexico and Central and South America and other sections contain rare and endangered Encephalartos and Stangeria from Africa, Macrozamia, Lepidozamia, and Bowenia from Australia, and Cycas from China and Vietnam.

Admission and directions:

Sadie Seymour Botanical Gardens (Kona)

The Sadie Seymour Botanical Gardens span 1.5 acres and give an overview of the native and non-native plants that inhabit the Hawaiian Islands. It is built in a series of terraces going down the mountain, each devoted to a separate ecosystem, e.g. native Hawaiian, Polynesian, South American, etc.

The property is also home to the Kona Outdoor Educational  Center and a Thrift store. The botanical gardens can be difficult to find because of the lack of signage if you don’t use GPS. Keep your eyes open for the thrift store flag at the top of the driveway and park on the upper level for the garden.

If you pass by and like to see botanical gardens make sure to stop here, but don’t plan your trip around these gardens. The botanical gardens at the Hilo side (especially the Hawaii Tropical Botanical Gardens) are far more impressive.

Admission and directions:

Admission to the Sadie Seymour Botanical Gardens is free but donations are accepted.

Address: 76-6280 Kuakini Hwy, Kona Outdoor Circle Educational Center. Phone number: 808-329-7286.

Gardens on the Big Island

The following two places are certainly worth the visit but don’t have as primary purpose the education of the visitor and the conservation and display of many plants and flowers.

Liliuokalani Gardens (Hilo)

The Liliu’okalan gardens are a Japanese garden located inside the 30-acre Liliu’okalan park. The gardens contain Waihonu Pond as well as bridges, koi ponds, pagodas, statues, torii, and a Japanese teahouse.
