If you have at least an eight-hour layover in Taipei, you can join one of two free city tours organized by the airport. Tour A ferries guests to the gorgeous Zushih Temple, about 14 miles outside of town, and on a trip to shop for pottery; Tour B packs in quicker stops to some of Taiwan's most famous sites, including the Chiang Kai-shek Memorial Hall and Taipei 101, the country's tallest building.

How to book it: Register at the Tourist Service Centre in the main arrivals hall. Tours are on a first-come, first-serve basis and offered twice a day (8:15 a.m. and 1:45 a.m.).
