ʻĪao Valley State Monument
ʻĪao Valley
A deep valley wrapped in rainforest, where the ʻĪao Needle, a vegetation-covered volcanic spire about 370 meters tall, rises from the valley floor. It was also the battlefield where Kamehameha unified Maui.
ʻĪao Valley lies on the east side of the West Maui Mountains, about 5 km from the town of Wailuku. Its iconic ʻĪao Needle is a lush volcanic spire rising about 370 meters above the valley floor. In 1790, Kamehameha I defeated the Maui forces here. Legend says the stream was dammed by the fighting, and the battle is known as the Battle of Kepaniwai. The park has short paved trails, viewpoints and a botanical garden, and can be toured on foot in about 30 minutes. Non-Hawaii residents must reserve entry and parking time slots in advance through the state park website. Check the website for current admission fees.
