The Ke'anae Arboretum is a small but charming arboretum and botanical garden built on ancient leveled terraces. Located along the meandering Pi'inau'au Stream, with over 150 labeled plants on six acres of land, the Ke'anaeArboretum is one of the best places to get some pictures of Hawaii’s uniquely famous plant life. Featured displays include blue marble trees, lobster claw plants and a grove of Maui’s famous rainbow eucalyptus trees. While you hike the half-mile length of the Arboretum, you’ll also find different types of taro, gingers, hibiscus, papaya, and a mix of native and non-native Hawaiian trees.
The rainbow eucalyptus tree is a rainforest spectacle, unique for its multi-colored bark which peels off in layers, leaving swatches of red, orange, green, blue and gray color on the trunk of the trees. Some rainbow eucalyptus trees can grow to more than 200 feet.
The Ke’anae Arboretum is located about .8 miles past the 16 mile marker on the Road to Hana, and the facility is open year-round, dawn to dusk. Hiking is suitable for all skill levels, and the main pathway is paved. There is a sharp, sloped curve in the road near the parking lot, so take care when crossing the roadway from the parking lot to the entrance to the park. There is no charge for entry. Mosquito repellant is highly recommended. Please be aware there are no washroom facilities at the Ke’anae Arboretum.
