Day one is for royal Seoul: Gyeongbokgung Palace, Bukchon Hanok Village and Insadong’s tea houses. Rent a hanbok for free palace entry.
On day two, head to Myeongdong and Namdaemun Market for street food, then ride the cable car up Namsan Tower for a night view.
Day three can be a day trip to Nami Island or the DMZ. Day four is for Hongdae, cafes and last-minute skincare shopping.
Do not skip the food: Korean BBQ, bibimbap, tteokbokki, hotteok and fried chicken with beer are all essential.
