4-wheel drive about a half-hour north from Lanai City and you’ll discover Kaiolohia, also known as Shipwreck Beach. This windy, 8-mile stretch of beach has wrecked numerous ships along its shallow, rocky channel. In fact, the hull of a ghostly oil tanker from the 1940s is still beached on Kaiolohia Bay’s coral reef, its rusted hull giving the beach a surreal sense of wonder. With excellent views of Molokai and Maui, this is a great area for beachcombing and exploring, but swimming is not advised. Beyond the beach, about 200 yards up a trail past the Shipwreck Beach sign are the Kukui Point petroglyphs, marked by reddish-brown boulders.
