Hawaii Tropical Botanical Garden, Big Island

This lush botanical garden just north of Hilo is a veritable museum of living plants and a fascinating place to explore. Botanists, photographers, scientists and tourists from around the world come to the Hawaii Tropical Botanical Garden to observe its rich flora representing over 2,000 species. The site offers visitors a chance to explore an authentic Hawaiian rainforest that's just chock full of life.

A raised wooden boardwalk leads you through a lush rainforest. You'll be able to see a variety of tropical flowers and plants, a waterfall and as you reach the shoreline, a picturesque bay. Due to its fertile volcanic soil and moist climate, the garden is able to support an exceptional bounty of species from around the world. More than 125 families and 750 genera are represented.

The garden is also home to a wide variety of fauna, including many colorful birds and reptiles. Here you'll find the gold dust day gecko, a native of Madagascar with striking yellow speckles along its neon green back. The Indian mongoose, a small, agile rodent introduced to the Islands in the 1880s, also makes its home here.

Resident bird species include the native 'auku'u (blue-crowned night heron) and the common mynah, which was introduced many years ago to control pests in the sugarcane plantations. Look closely and you'll also find the 'a'ama crab, a tree-climbing crab that moves faster than you can say "aloha." Common insects include the Sphinx moth and the yellow and black garden spider.

Frequently Asked Questions

Why is Onomea Valley important to the garden?

Onomea Valley gives the garden its sheltered rainforest setting. The steep valley, streams and ocean-facing lower section create the wet, green environment that supports the plant collections.

What makes the garden different from a flat display garden?

The route drops from the entrance into a natural valley, so the visit feels more like a rainforest walk than a single flat garden loop. Bridges, slopes, ponds and stream crossings shape the experience.

Why do photographers like Hawaii Tropical Botanical Garden?

The garden has many close-up subjects in a compact area, from orchids and bromeliads to palms, waterfalls, lily ponds and the darker greens of the valley.

How does the Hamakua Coast setting affect the garden?

This windward side of the island receives frequent moisture, which helps keep the valley lush. It also means the garden can look different after rain, with fuller streams and deeper rainforest color.

What is the connection between the garden and Onomea Bay?

The lower garden opens toward views of Onomea Bay, adding a coastal finish to the rainforest route. It is one reason the garden feels connected to both valley and ocean.
