Chinaman's Hat, officially known as Mokolii Island, is a small, picturesque island located off the coast of Kaneohe Bay on Oahu's Windward side. The island gets its nickname from its shape, which resembles a traditional Chinese conical hat. It’s a popular spot for kayaking, paddleboarding, and snorkeling. The island is accessible by a short kayak or boat ride from the mainland, and its shallow waters and scenic views make it a favorite destination for outdoor enthusiasts and photographers.
