If you have more time, you could visit some museums, such as the National Museum of Modern and Contemporary Art or the War Memorial of Korea. For foodies, street food tours through Myeong-dong or Korean BBQ tours are also worth considering.If you have less time, you can skip one district and instead visit the Cheonggyecheon Stream for a peaceful stroll along the water or Lotte World for some indoor theme park fun. Travelers with a love for K-Pop and Korean dramas should visit the SM Town at COEX Artium Building or the JYP Entertainment building to spot K-Pop idols.
