Hazard Rock Mitigation Fence and Trail Improvement Projects Update: It was the trail program’s intention to keep the trails open on weekends during the projects. However, as heavy rainfall continues to create extremely muddy and slippery conditions. Trail staff has determined that the Manoa Falls and Aihualama trails are currently unsafe for hiking and will, therefore remain closed until further notice. We ask for your patience as the contractor and Na Ala Hele staff work diligently to finish the two projects and reopen the trail. Keep checking this website for updates.

2. Via Manoa Falls Trail: Follow Manoa Road into the back of Manoa Valley. Manoa Road ends at Paradise Park. Continue up the road, through the parking lot, towards the entrance of Lyon Arboretum. At the sharp left bend in the road to Lyon, proceed straight ahead. This is the Manoa Falls parking area and trail head. Hike 0.8 miles on Manoa Falls Trail. Approximately 150 feet from the base of the Falls, there is a marked trail that proceeds left. This is Aihualama Trail.

Please note that Aihualama Trail (in yellow) is part of the Honolulu-Mauka Trail Network, comprising of 18 interconnected trails (in turquoise).

Plants & Birds

Along the way 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.

Lining the middle switchbacks of the `Aihualama Trail are ki (ti) plants. They have shiny leaves, 1-- 2 feet long that are arranged spirally in a cluster at the tip of a slender stem. Early Polynesian voyagers introduced ti to Hawai`i. They used the leaves for house thatch, skirts, sandals, and raincoats. Food to be cooked in the imu (underground oven) was first wrapped in ti leaves. A popular sport with the commoners was ho`ohe`e ki or ti-leaf sledding. The sap from ti plants stained canoes and surfboards.

History

The `Aihualama area has a long and colorful past. The first scene of the grisly Hawaiian legend of Kahalaopuna takes place along `Aihualama Stream. In 1895, royalist rebels fleeing government forces used an old Hawaiian trail along the stream as an escape route after a skirmish at the back of Manoa Valley. The royalists had tried to overthrow the recently founded Republic of Hawai`i and return Queen Lili`uokalani to the throne.

In 1919, the Hawaiian Sugar Planters Association (HSPA) established a small station, later known as Lyon Arboretum, in the `Aihualama area to carry out reforestation projects. For easier access to the mauka (inland) section, HSPA crews built a trail that switchbacked up the steep slope to Pauoa Flats. In 1978, volunteers under the direction of the Sierra Club, Hawai`i Chapter, restored the deteriorated arboretum switchbacks and built a new contour route connecting them with the Manoa Falls Trail.
