Fashion- and technology-forward but also deeply traditional, this dynamic city mashes up palaces, temples, cutting-edge design and mountain trails, all to a nonstop K-Pop beat. Whatever you want, at any time of day or night, Seoul can provide. An early-morning temple visit can lead to a palace tour followed by tea-sipping in Bukchon and gallery-hopping in Samcheong-dong. Soju (a vodka-like drink) and snacks in a street tent bar will fuel you for shopping at the buzzing Dongdaemun or Namdaemun night markets, partying in Hongdae or Itaewon, or singing in a self-service karaoke noraebang. Follow this with steaming, soaking and snoozing in a jjimjilbang (sauna and spa). By the time you look at your watch, it will be dawn again. Public transport is brilliant, so there’s no excuse for not stretching your travel horizons beyond the city limits. The fearsome Demilitarized Zone (DMZ), splitting South from North Korea, exerts a powerful attraction and makes for a compelling day trip. To the west, Incheon is a fascinating port where the modern world came flooding into Korea at the end of the 19th century, and today whose Chinatown and waterfront are still an interesting fusion of people. To the south is Suwon, home to impressive World Heritage–listed fortifications, built by King Jeongjo, that snake 5.7km past majestic gates and pavilions.
