World-famous Ha Long Bay (located about 100 miles east of Hanoi), one of the UNESCO World Heritage Sites). This bay contains about 2,000 of these rock islands and was featured in the movie "Indochine" and the James Bond flick "Tomorrow Never Dies." These pictures really don't convey just how huge these rock islands are -- or how beautiful they are to see in person.
