About Maunawili Falls State Park

 

Maunawili Falls State Park is located on the windward side of Oahu, Hawaii, covering a region rich in tropical flora and fauna. The park’s centerpiece is the Maunawili Falls, a 20-foot waterfall that cascades into a large pool popular for swimming and cliff jumping by visitors. The area’s geography includes steep valley slopes and dense rainforest vegetation that support native species alongside tropical plants like bamboo, ferns, and kukui trees. Historically, the region was part of the land used for taro cultivation and places cultural significance on Hawaiian traditions. The main recreational opportunity is the Maunawili Falls Trail, a roughly 3-mile round trip hike that features crossings of the Maunawili Stream, a mix of shaded forest paths, and sections with scenic views. The trail has variable terrain and river crossings that can be challenging after heavy rain. Apart from hiking and swimming, the park offers chances for birdwatching and photography. Maunawili Falls State Park’s accessibility and natural beauty make it a favored destination for both locals and tourists seeking a moderate outdoor adventure on Oahu. The falls themselves serve as a rewarding destination after a forest hike and provide a refreshing swimming experience in a tropical setting.
