Hau`ula Loop Trail begins on the right side of the access road, just past the hiker/hunter check-in station. Where the trail branches off, take the right fork which climbs up the adjoining ridge. It crosses Waipilopilo Gulch, then travels makai (towards the ocean) on the next ridge overlooking Kipapau Valley to return back across the gulch, around the makai side of the ridge, and rejoins the start of the trail. This trail goes through groves of planted ironwood. It also offers great views of Hau`ula and the ocean. Remnant native species in the Waipilopilo Gulch include lama, alahe`e, `ohi`a, hoawa, akia and a`ali`i. This trail is a good family trail. 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.
