Hale'iwa Ali'i Beach Park, Oahu
Located west of the Hale'iwa Small Boat Harbor, this 19-acre beach park is a favorite gathering spot among North Shore residents.There is a large grassy area with plenty of room for a picnic. A recreation center named Kalili Surf Center is located in the park.
A popular surf site called Hale'iwa is located offshore. Beginners usually stick closer to shore, while experts ride the higher waves further out. A few surfing contests take place here in the winter months, when the surf on Oahu's North Shore is up.
There are also a few good dive sites offshore, such as the Hale'iwa Trench, a man-made dive site built by the military during World War II to hide submarines. The trench features a dramatic drop from a shallow reef to depths of around 90 feet and attracts a wide variety of marine life, such as green sea turtles, octopuses, eels and reef sharks.
Swimming is possible here, but the conditions are fair because the ocean bottom is rocky. The beach park is more suitable for surfing, kayaking, boating, fishing and diving.
