At 16,000 acres, Lana'i is one of the largest pineapple plantations in the world. Castle and Cooke Corporation, a subsidiary of Dole Company, privately own more than 98 percent of the island. Situated in the rainshadow of the West Maui mountains, Lana'i experiences sparse rainfall, which is ideal for its agricultural mainstay.
Throughout the coastal areas of the island are the remnants of past civilizations. Several heiaus and concentrations of petroglyphs are accessible by four-wheel drive vehicles and a good pair of hiking boots.
Most diving charters to the island of Lana'i originate from Lahaina on Maui. Travel time ranges from 45 minutes to one and a half hours depending upon the speed of the boat, the surface conditions on the 'Au'au channel, the site destination and what kind of distractions might be encountered along the way.
The majority of diving off Lana'i is done along the south coast, with a couple of sites on the western and eastern sides. The shoreline walls surrounding many areas of Lana'i are so precipitous they look like the island was shaped with an icing knife at the time of its creation. Formations of ridges, pinnacles, lava tubes and caverns provide the topographic setting for interesting and varied underwater exploration.
