Route: Printable Topographic Maps Wiliwilinui Trail begins on a dirt access road through formosa koa and guava forest. As the road climbs up the ridge, it becomes native koa-uluhe forest. The trailhead is about 1.5 miles up the access road. The trail climbs straight up the ridge to a HECO tower. Continue past the tower to the Koolau summit. This trail offers opportunities for viewing a variety of native plants and, from the summit, the leeward coast and Waimanalo. Note: The Wiliwilinui Community Association has been more than cooperative in letting hikers and hunters access State land through their property. Please abide by all rules and regulations of the association.
