NOTICE: Entire Moanalua Section of the Honolulu Watershed Forest Reserve, will be closed for a minimum of 30 days (or longer if necessary) due to the removal of the Ha‘ikū Stairs. The closure encompasses the area bounded by the Kulanaʻahane Trail to the north, Kamananui Valley Road, and an unofficial trail known as Waolani to the south, and the Koʻolau summit ridgeline to the east. This closure is enacted to protect biological resources, ensure public safety, facilitate property management, and prevent ecological damage to the sensitive native forest. Middle Ridge, though not an official trail, has experienced increased erosion and safety risks due to heightened hiker traffic. Unauthorized trail use during this time may result in citations. While the Kulanaʻahane Trail and Kamananui Valley Road remain open, we urge visitors to utilize designated Nā Ala Hele trails and respect nature's balance while enjoying recreational activities.
