About Nāpu‘u O Walākea Forest Reserve

 

Nāpu‘u O Walākea Forest Reserve is located on the eastern slopes of Mauna Kea on the Big Island of Hawai‘i. Established to protect the unique native forest ecosystems found here, the reserve includes dense stands of ʻōhiʻa lehua and koa trees, which are critical habitats for native Hawaiian birds and rare plants. The region's elevation ranges from approximately 4,500 to over 6,000 feet, creating a cool, moist climate that supports a vibrant montane ecosystem. Historically, this land was used by native Hawaiians for forest resources and cultural practices, and today it serves as a conservation area managed by the Hawai‘i Division of Forestry and Wildlife.

Visitors to Nāpu‘u O Walākea Forest Reserve can enjoy peaceful hikes on well-maintained trails that meander through pockets of native forest, birdwatching for endangered species like the Hawai‘i 'Amakihi or 'Apapane, and experiencing rich cultural connections to the land. The reserve contains several lookout points offering sweeping views of Hilo and the surrounding valleys. While it remains relatively undeveloped, its pristine condition provides a valuable glimpse into Hawai‘i’s natural heritage and an important sanctuary from invasive species and forest pests. It is part of a network of protected areas contributing to Mauna Kea’s watershed health and native species survival. Outdoor enthusiasts, birders, and cultural history seekers alike find Nāpu‘u O Walākea a rewarding destination for quiet exploration and nature immersion.
