Route Description

Waimano Trail begins at a chain link fence next to the parking area. You will quickly come to a fork where lower Waimano Trail splits from upper Waimano Trail. They form a loop. Lower Waimano Trail continues on an old jeep road to the floor of the valley and then follows the stream for a distance up the valley. The trail will then climb back uphill to join the upper Waimano Trail. The upper trail goes continues from the split along the road for 0.5 mile. It then turns left and follows a ditch and tunnels to an intake in the east branch of Waimano Valley. It then climbs over a ridge and continues along a stream to an old abandoned dam. The trail then goes slightly to the right, makes several switchbacks and then continues gradually up to the Ko‘olau summit. This trail offers a wide variety of native and non-native vegetation and spectacular views of Waimano Valley. From the summit, the ends at a view of the windward side of O‘ahu. This trail traverses a public hunting area - hikers should exercise caution. Wear bright colored clothing and be aware that you may encounter hunters who may be hunting off trail - stay on the trail.
