Iao Valley State Park and Pu'u Kukui Crater

Iao Valley (iao is sometimes translated as "highest cloud" or "highest light") lies west of Wailuku on road 32, the continuation of Main Street, and used to be one of the old Hawaiian holy valleys. Hawaiians would undertake pilgrimages to such places in honor of their gods.

Today, several well-maintained paths lead from the car park to this beautiful valley. It is a popular place for excursions.
