Mahukona Beach Park is located on the northwest shore of the Big Island, Hawaii, and is situated on the site of an old sugar company property. It offers a unique blend of natural beauty and historical significance, with remnants of the sugar mill still visible. The beach itself is approximately 500 feet long and features black sand and crystal-clear waters, making it a popular spot for swimming, snorkeling, and scuba diving. The protected harbor provides calm conditions ideal for these activities.
The park's surroundings include a large concrete dock with a rusting crane, adding to its industrial charm. Visitors can explore the nearby trail leading to a light tower or visit the adjacent Lapakahi State Historical Park, which preserves ancient Hawaiian archaeological sites.
Mahukona Beach Park has a local feel, especially on weekends and evenings, and allows alcoholic beverages from 10 am to 10 pm.
