South Korea has become one of Asia's most compelling travel destinations, and not just because of K-pop and K-drama (though both are very much on display in Seoul). The capital is extraordinary: ultra-modern infrastructure layered over ancient palace grounds, a street food scene centred on Myeongdong and Gwangjang Market, and a nightlife district in Itaewon that runs until dawn.
Beyond Seoul: Busan's coastal energy and Jagalchi fish market, the preserved Hanok village of Jeonju, the volcanic island of Jeju, and the ski resorts of PyeongChang in winter.
