Kahana Bay Beach Park is located on Oahu's windward coast, nestled within the majestic Ko'olau Mountains. This scenic spot boasts a crescent-shaped shore lined with ironwood trees, offering ample shade for picnics and relaxation. The beach is ideal for sunbathing, though swimming is less popular due to the murky water from Kahana Stream and a rocky nearshore ocean bottom. It's a great place for barbecue and offers picnic areas, making it perfect for family outings or camping, which requires a permit.
The beach is also home to an ancient Hawaiian fishpond called Huilua, adding historical interest to its natural beauty.
Local residents often visit here for camping on weekends, which can make the beach busier during those times.
