I'ao stream tumbles along the sharp crevice at the bottom of two ridges extending down the walls of Pu'u Kukui Crater as it makes its way to the sea.
The 6.2-acre park features a paved trail through a botanical garden featuring plants brought to the valley by early Hawaiians who settled there.
The park features easy-access, railed pathways, paved parking, restrooms and stunning views. However, there is no drinking water.
The park is open from 7 a.m. to 7 p.m. but I'ao Needle is often shrouded by low-lying clouds as the day progresses, so early mornings offer the best views.
