An amazing dive for intermediate through advanced divers. The best time to dive this site is during the summer months when surf is low and current is almost none. Diving the Haleiwa "trench", as it is called, is best done at night and is requires a small swim to get to the primo spot, but once found the site contains all sorts of special treats such as dragon morays, harlequin shrimp, white tip reef sharks, lobsters, and more!!!! If you are into spearing, this site has an abundance of 1-2lbs. Kumu (goat fish).
