Atlantis Submarines (part of Atlantic Adventures) has been exploring the undersea wonders of Hawaii since 1988. Using battery-powered environmentally safe submarines in Waikiki, the company takes passengers over 100 feet (30.5m) deep, past famous dive sites like Leahi (Diamond Head) which is frequented by green turtles, sharks, stingrays and eels. In Maui, visitors can discover the Atlantis Undersea Adventure and see some truly spectacular marine life there too.
