Ke'anae Arboretum is a tranquil, free botanical escape on Maui's famous Road to Hana. This six-acre botanical haven showcases over 150 species of tropical plants from around the world, offering a serene retreat amidst Maui's verdant beauty. It's a must-visit destination for nature enthusiasts seeking a peaceful interlude along their scenic journey.
The arboretum's star attractions include the vibrant Rainbow Eucalyptus trees, renowned for their striking multi-colored bark that peels to reveal mesmerizing hues of green, blue, purple, orange, and maroon. Visitors can also explore a rich collection of native Hawaiian flora and significant "canoe plants" such as breadfruit, papaya, ginger, hibiscus, and various types of taro. A well-maintained 0.6-mile paved walkway guides visitors through this diverse landscape, leading to historically significant taro cultivation terraces, known as *loʻi kalo*.
Each plant is thoughtfully labeled with common and scientific names, as well as its origin, providing an engaging educational experience for all ages. Beyond the botanical wonders, the arboretum offers a fascinating glimpse into ancient Hawaiian agricultural practices and a deeper connection to the island's rich cultural history. It’s a perfect, free respite from the winding Road to Hana, offering countless opportunities for beautiful photographs and a memorable encounter with Hawaii's natural splendor. Don't forget to bring the Snappit nature identification app along to scan local species.
Before the 1940s, the land that now comprises the Ke'anae Arboretum was utilized for farming various food, medicinal, and fiber-producing plants. From 1946 until the mid-1950s, it served as an agricultural work site for prisoners at the Keʻanae Prison Camp. The Keʻanae Arboretum was officially established in 1971, transforming into a dedicated space for the conservation and display of tropical plant species. The arboretum is uniquely situated on ancient terraces, or *loʻi*, historically built and used by Native Hawaiians for cultivating taro, a staple crop central to Hawaiian culture and sustenance.
Stroll along the paved 0.6-mile path, admire and photograph the distinct Rainbow Eucalyptus trees, observe the meticulously labeled plant species, and learn about the historical taro patches. Visitors can also cool their feet in the natural pools of the Pi'ina'au Stream if water conditions are clear.
The climate is warm and humid with frequent showers throughout the year. Mosquitoes can be particularly active at certain times, so be prepared.
The main path, approximately 0.6 miles long, is paved and well-maintained, making it accessible for families with children and strollers.
