Improvements to Diamond Head Trail on Oahu are taking longer than originally planned. The trail was slated to re-open yesterday but now the estimated completion is early March.
The trail is open regular hours on weekends and holidays but closed half-days during the week. The Hawaii Department of Land and Natural Resources says more than 2,500 visitors use the trail each day and that had caused conditions to deteriorate, prompting the million-dollar project.
The contractor has completed major repairs to the trail surface, but the DLNR says “is needing additional time to complete the anchoring of areas along the trail with rockfall potential. They are also improving drainage along the trail to help mitigate erosion and direct any water off the trail. While active work is in progress the trail must be closed for public safety and no bypass is available.”
The crater access road is not affected and the park area inside the crater is still open normal daily park hours. For the next month, the trail is generally closed weekdays from noon to 6 pm. If you want the exact schedule, it is available on line or on a telephone recorded message.
Later this year, a third phase of the trail improvement will begin. That will construct a new loop trail and repair the narrow ledge where hikers leave the fire control station at the summit. Partial trail closures will also be needed then but the date has not yet been set.
