This was once a harbor used by a local sugar company. There is no beach here, but it is a good place to snorkel or dive and explore the abundant fish life. Abandoned mill equipment and an old shipwreck sweeten the underwater experience. Restrooms and drinking water are available. Just a mile up the road is Kapa'a Beach Park, another good snorkeling and diving spot.
The waters are generally calm and clear to showcase the underwater view. A picnic pavilion with barbecue pit is available.
To get to Mahukona take Highway 270 north from Kawaihae. Take the road to the ocean between mile markers 14 and 15.
