Nanakuli Natural Area Reserve is a protected coastal and watershed area on the island of O‘ahu, Hawaii, notable for its native dryland forest, native species habitat, and scenic coastal views.
Nanakuli Natural Area Reserve is located on the leeward coast of O‘ahu, Hawaii, encompassing a mix of rugged coastal cliffs, native dryland forest, and important watershed areas. The reserve covers nearly 1,000 acres and serves as a critical habitat for rare plant species and native birds, such as the ‘Akiapōlā‘au and Olomao. The area's geology includes dramatic lava formations and steep cliffs dropping toward the Pacific Ocean, offering scenic vistas and coastal ecosystems that are rare on O‘ahu. Historically, the site holds significance tied to Native Hawaiian land use, including traditional gathering practices and cultural preservation efforts. Visitors to Nanakuli Natural Area Reserve can enjoy low-impact hiking and wildlife observation, particularly of endemic flora and fauna, but access is carefully regulated to protect fragile environments. The reserve is part of the state’s Natural Area Reserve system, designed to maintain biodiversity and limit development. Though it lacks formal trails and developed visitor facilities, it is valued by researchers, conservationists, and visitors seeking to experience Hawaii's native landscapes with minimal disturbance. The reserve’s proximity to the community of Nanakuli also reinforces its cultural and environmental importance as a place for education and stewardship.
