Hawaii: Flight time from L.A. 5 hrs 45 minsThe Hawaiian archipelago is a child of volcanic chaos. And underwater is the best place to witness the effects of nature’s most extreme displays of tectonic energy. The seafloor reflects these molten origins, with its labyrinth of lava tubes and tunnels, caverns and pinnacles. Beyond the topography, the islands offer a diverse variety of diving delights: the pelagic playground of the Big Island, Maui for Molokini, sharks and cathedral caverns off Lanai, Oahu for a wealth of wrecks and Kaui for monk seals and sea turtles. Topside, Hawaii feels primal, paradisiacal and peaceful, with irresistible mana (spirit) that will wrap you in its embrace and never let go.
