Seoul is a hyper-connected capital where K-culture meets ancient dynasties — Gyeongbokgung Palace, Korean BBQ, Myeongdong shopping, and the DMZ tour define it.
Seoul is where K-pop meets the Joseon Dynasty -- a hyper-connected capital where 600-year-old palaces like Gyeongbokgung and Changdeokgung stand beside K-beauty stores and neon-lit Gangnam. The food scene from sizzling Korean BBQ with unlimited banchan to street topokki at Gwangjang Market makes Seoul worth the trip. The city has the fastest average internet speed in the world and ubiquitous free WiFi. Hongdae pulses with indie music and youth fashion while Insadong's tea houses showcase traditional culture.
April and May bring cherry blossoms and pleasant 12-20 degrees C. September through November offers autumn foliage at Namsan with cool clear weather -- the best season. Winter (December-February) is cold at -5 to 5 C but cheapest flights and beautiful light festivals. Summer (June-August) is hot and humid at 25-30 C with monsoon rains in July. The rainy season runs late June to late July. Chuseok in September-October is a major holiday.
