Route: 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 of 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.

Directions: From Kalanianiole Highway heading east, turn left on Laukahi Street. Continue mauka (toward the mountain) on Laukahi until you come to a security guard station. Check in with the security guard and then proceed up Laukahi until it ends. Turn left on Oko`a, following the trail signs. Park in the parking area before the cable gate and proceed on foot along the access road to the trailhead..
