Today is a full free day for you and your family to explore Seoul and choose from the many optional activities on offer. Try to keep up with the kids in a fun Taekwondo or K-pop dance class or visit some of the many museums, parks or kids cafes dotted around town. Venture into nearby districts like modern, upscale Gangnam for a hit of local Hallyu culture, or Hongdae - a popular area for urban art with the young locals. Here, you can see street musicians and artists, wander through the many shops and cafes or, if visiting in summer, you can cool off in one of the outdoor swimming pools along the Han River. With so much to see and do, it's guaranteed to be a full-filled day.
