From Kamehameha Highway in Hau‘ula, turn onto Hau‘ula Homestead Road (across from Hau‘ula Beach Park). When the road makes a sharp curve to the left, continue straight onto the access road. Park along the road before the cable gate, taking care not to block the gate. Continue on foot past the gate and the hunter/hiker check-in station. Hau‘ula Trail begins on the right side of the access road, just past the check-in station.

Dog Owners

Hunting may be in progress on or near this hiking trail. Hunting dogs may be off-leash while engaged in the hunt. Hikers must keep their dogs leashed at all times and remove dog waste while on this trail.

Plants & Birds

On the trail, look and listen for the white-rumped shama. It is black on top with a chestnut-colored breast and a long black-and-white tail. The shama has a variety of beautiful songs and often mimics other birds. A native of Malaysia, the shama has become widespread in introduced forests such as this one.

Above Kaipapa`u (shallow sea) Gulch on the Hau`ula loop are a few pukiawe shrubs and `ohi`a trees. Pukiawe has tiny, rigid leaves and small white, pink, or red berries. `Ohi`a has oval leaves and clusters of delicate red flowers. Early Hawaiians used the flowers in lei and the wood in outrigger canoes. The hard, durable wood was also carved into god images for heiau (religious sites).

On the return leg of the Hau`ula loop is a forest of tall Cook pines planted by Territorial Forestry in 1933. They have overlapping, scale-like leaves about 1/4 inch long, rather than true needles. Named after Captain James Cook, they are native to New Caledonia (Isle of Pines) in the South Pacific between Fiji and Australia.

History

In the early 1930s Territorial Forestry built the Hau`ula Loop to provide access to the Hau`ula Forest Reserve for tree planters, pig hunters, and fence builders. Trail crews started digging out the loop in January 1933 and finished it in April of the same year. Civilian Conservation Corps workers re-graded and cleared the Hau`ula Loop in 1935.

Route Description

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.
