Ke'anae Arboretum is a 6-acre botanical garden located along the Hana Highway in north eastern Maui, Hawaii. Open to the public without charge, the arboretum was developed in 1971, under the supervision of Forest Ranger Henry C. Inciong, to preserve and showcase both native and introduced plants in a natural setting.
The arboretum lies alongside the Pi'ina'au Stream and features numerous paved trails that let visitors get up close and personal with the site's lush vegetation with ease. On sloping areas are terraces containing taro, built hundreds of years ago. Taro is an important food crop of the ancient Hawaiians.
Another path takes visitors through timber, fruit, and ornamental trees from tropical regions around the world. There are about 150 varieties of tropical plants, including gingers, hibiscus, papaya, and various types of taro, as well as native and introduced trees in the arboretum including the painted bark eucalyptus trees. Plants and trees are labeled with common name, scientific name, and origin.
The Ke'anae Arboretum is open daily and is located around half-mile beyond mile marker 16 on the Hana Highway. A sign on the mauka side of the road marks the entrance to the arboretum.
