Honolulu Watershed Forest Reserve (Moanalua section). Easy hike through the lush forest of Kamananui Valley. A City and County park provides bathrooms, potable water and garbage cans at the trail head. No such facilities are available within the valley itself. Non-potable stream water can be found through out the valley. All water should be treated. As access to campsites requires stream crossings, IT IS NOT RECOMMENDED TO HIKE THIS TRAIL DURING HEAVY RAINS due to the possibility of flash flooding.
Campsites not designated. Camping is allowed anywhere within the trail corridor (10 feet from center line) except for at the "Education Forest Project Site." The Education Forest Project Site is located approximately 150 yards past the large screen gate on the Ewa side of the road. This space must be kept available for our education field trips. The purpose of the site is to bring K-12 students into the forest and to teach them about natural resource management including native species and invasive species. The students help to malama the site by planting native plants, removing weedy species, learning about research taking place in the Forest Reserve, making leaf rubbings and other fun learning activities. For more information contact Michelle Jones at (808) 587-4188.
