The island of Lana'i offers some of the best diving in Hawaii. Lana'i is the sixth largest island in Hawaii. Lanai is known as the pineapple island due to its history as a island-wide pineapple plantation. In 1922 James Dole purchase the entire island. Lanai has a single city, Lanai City and it contains fewer than 5000 residents. The sparse population on Lanai and the island's remote location translates into more fish, less water pollution, and better diving than Maui and Oahu. The south side of Lanai is where all the diving is done. Often times Lanai is sheltered from North and South swells seriously affecting other parts of the island. The underwater topography consists of lava formations including caverns, walls, "cathedrals," tubes, and pinnacles. Turtles off Lanai are not affected by the herpes-like virus plaguing the Maui turtles. The ʻAuʻau channel seperating Maui and Lana'i is the most common place to find whales since it's the most protected and shallow place for the Humpback Whales. Lana'i also offers a pod of spinner dophins frequently seen during dive trips over to Lana'i. Lana'i offers incredible dive sites, amazing whale watching and dolphin opportunities.
