Plants & Birds
Lining the switchbacks of the Nahuina 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.
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.
Always yield to hikers. Do not slide around corners or slide down the trail. Careless mountain biking damages the trail and causes erosion. If accidents are reported or damage to the trail is extreme, the trail may be closed to mountain bikers. This trail is not an easy mountain bike trail.
If driving, proceed mauka on Tantalus Drive. When you get close to the top, look for the trailhead sign behind the guardrail on the right side of the road. There is trail parking in the small lot just before the trailhead on the left side of the road.
Please note that Nahuina Trail (in yellow) is part of the Honolulu-Mauka Trail Network, comprising of 18 interconnected trails (in turquoise). The system may be accessed via the Makiki Arboretum Trail (dark blue) as part of an extended hike. The shortest route from the Makiki Arboretum Trail to the Nahuina trailhead is 1.4 miles.
The Nahuina Trail starts at a signed junction by the guardrail along Tantalus Dr. Descend gradually on four long switchbacks. Contour along the side of a ridge, crossing several gullies. Reach the end of the Nahuina Trail at a signed junction with the Makiki Valley Trail.
