ʻIao Needle Lookout Trail and Ethnobotanical Loop

‘Iao Valley State Monument will be CLOSED beginning MONDAY, OCTOBER 16, 2017 for an estimated two months. The Department of Land and Natural Resources (DLNR) will be completing the second phase of slope stabilization to the areas in the park that were damaged by a massive flood event in September 2016. We anticipate the park will reopen by December 16, 2017, or sooner if conditions permit.

Trail Length 0.6 miles
Activity Pedestrian
Difficulty Easy
Terrain Wet Valley
Elevation Gain 200 ft
Park Name ‘Iao Valley State Monument


Please watch this video explaining the reasons for the temporary closure.

A paved walking trail provides a scenic viewpoint of Kuka’emoku (‘Iao Needle), an erosional feature which rises 1200 feet from the valley floor. A short paved loop trail meanders though an ethnobotanical garden adjacent to ‘Iao stream.


Trail begins just beyond the park restroom and interpretive signs. The path crosses a bridge over the stream and climbs to the lookout point, where a small shelter is nestled.


End of ‘Iao Valley Road (Highway 32), ‘Iao Valley.
