Puʻu ʻŌhiʻa Trailhead on Tantalus Drive in Honolulu, Hawaii offers cool native forest hiking, sweeping city views, and a network of interconnected ridge trails.
Puʻu ʻŌhiʻa Trailhead sits on Tantalus Drive in the forested hills above Honolulu, within the broader Honolulu Watershed Forest Reserve that protects the slopes of the Koʻolau Range. The area takes its name from the native ʻōhiʻa lehua, one of Hawaii's most ecologically important trees, whose red blossoms dot the canopy throughout the year.
The trail network here connects hikers to several routes ranging from gentle forest walks to more demanding ridge climbs. A popular option follows the Makiki Valley loop system, weaving through bamboo groves and past introduced tropicals alongside pockets of restored native vegetation. You can also reach the nearby ʻAihualama Trail, which descends toward Mānoa Valley through dense, atmospheric forest.
Elevation gains along these trails reward hikers with views stretching across Honolulu to the ocean, and on clear days the outline of neighboring ridges stands sharp against the sky. The forest itself is the main draw, offering birdsong, cool air, and a quietness rare for a trailhead so close to a major city.
For those wanting to extend the adventure, the Mānoa Falls Trail is a short drive away and pairs naturally with a morning at Puʻu ʻŌhiʻa. Few green spaces in Hawaii deliver this combination of accessibility and genuine wilderness feeling.
Visit early in the morning, ideally before 9 a.m., when the forest is coolest and the mist still clings to the ridges.
Wear trail shoes with solid grip, as the path can be muddy and slick year-round due to the area's high rainfall.
Bring a light rain jacket even on sunny days, since conditions on Tantalus can shift quickly from clear to overcast.
Combine your hike with a stop at Tantalus Lookout at Puʻu Ualakaa State Park nearby for a sweeping panoramic view of Honolulu.
Pack out everything you bring in, as this trailhead has no trash facilities and the forest ecosystem is sensitive to disturbance.
