Towering emerald peaks guard the lush valley floor of ʻĪao Valley State Park. Located in Central Maui just west of Wailuku, this peaceful 4,000-acre, 10-mile long park is home to one of Maui's most recognizable landmarks, the 1,200-foot ʻĪao Needle. This iconic green-mantled rock outcropping overlooks ʻĪao stream and is an ideal attraction for easy hiking and sightseeing.
Aside from its natural tropical beauty, sacred ʻĪao Valley has great historical significance. It was here in 1790 at the Battle of Kepaniwai that King Kamehameha I clashed with Maui's army in his quest to unite the islands. Even with ʻĪao Needle serving as a lookout point, Kamehameha defeated Maui's forces in a ferocious battle that ultimately changed the course of Hawaiian history.
There is a well-marked, paved pedestrian path leading from the parking lot to view ʻĪao Needle and the ridge-top lookout provides incredible views of the valley. The needle is sometimes covered in clouds, so an early start is your best bet for a good view. Families can also take a rainforest walk or explore interactive exhibits at the Hawaiʻi Nature Center, which is also located within ʻĪao Valley. Restroom facilities are available.
