Taipei (Taiwan)

The safest big city in Asia is also one of the friendliest. Night markets are social hubs where you bond with locals over stinky tofu and bubble tea. The MRT system is spotless and intuitive. Taipei's mix of hot springs, hiking trails, and 24-hour bookstores creates a city that caters to every solo traveler mood — adventurous, contemplative, or just hungry at 3am.
