Iao Valley State Park

Experience lush beauty in the waterfalls and pools of Iao Valley.

Iao Valley State Park is known for iconic views of the Iao Needle, but Iao Stream offers park visitors a more hands-on, jump-right-in experience.

The stream cascades through Iao Valley, and its cooling waters form mini waterfalls and tranquil pools that make for a refreshing escape.

Iao stream is known as one of Na Wai Eha (Four Waters of Maui) as its water was used to feed kalo (Taro) fields that thrived lower in the valley 200 years ago. In recent years, the water was diverted to irrigate sugarcane fields.
