This dirt and gravel road goes uphill west of Ahumoa to the historic Puʻu Lāʻau Ranger cabin, passing through open māmane (Sophora chrysophylla), naio (Myoporum sandwicense), and ʻiliahi (Santalum paniculatum) native high-elevation dry forest. Native forest birds such as ʻamakihi (Hemignathus virens) and ʻelepaio (Chasiempis sandwichensis) are often sighted in the vicinity of the road. The route also traverses critical habitat of the endangered palila (Loxioides bailleui), a Hawaiian finch found only on the upper slopes of Mauna Kea.

• In order to use the Mauna Kea Riding Area, you are required to obtain a permit and complete a waiver agreement which is available FREE online at the link below (See "Links" section).

Special Conditions

Wear bright colored clothing as the road passes through areas for year-round archery hunting for game mammals and seasonal shooting of game birds. Occasionally, the area may close due to aerial control of invasive mammals. Further information may be obtained by contacting the Division of Forestry and Wildlife at (808) 974-4221.

Do not use any trail or access road that is not delineated by name and color and that may also be displayed on these maps. The marked features are managed for public recreational use. Other trails or roads that branch off from the public features may be on private property, and are not managed for any public recreational use. Access is subject to adjacent landowner approval, and if used without authorization, you will be trespassing and possibly putting yourself at risk.
