Many choose the Micronesian volcanic island of Saipan to tour the famous Grotto, an underwater limestone cavern plummeting seventy feet at its deepest point. The Grotto is home to a city of sea life, including turtles, coral, and reef sharks.  Land-lovers can find satisfaction in the Garapan Street market, a display of Saipan's unique food and craft tradition, or the World War II battlefields, a visual history of the Battle of Saipan.
