In partnership with The Catlin Seaview Survey, Mountain View created the on-rails snorkeling experiences using undersea pictures from Heron, Lady Elliot and Wilson Islands at the Great Barrier Reef, Molokini Crater and Hanauma Bay in Hawaii and the Apo Islands in the Philippines. Combined with views from Chichen Itza and Teotihuacan, the new underwater tours might make for a respectable, desk-based vacation.
