During my exchange in Hanyang University, I managed to participate in various uniquely Korean experiences.
One of the most unique experiences Korea offers is the jjimjilbang (Korean traditional sauna). It is a place where you can relax and enjoy various wellness facilities such as baths, massage chairs, sleeping rooms and of course the highlight, a charcoal sauna that goes up to 80 degrees. Usually, you would take a bath and then relax in the heated room and then come out to get some ramen, charcoal eggs and a cup of cool sikhye (rice punch). The wooden interior of the jjimjilbang also aids in the ambience and with the many facilities makes for a highly pleasant and comfortable experience.
Another unique experience in Korea is the coin noraebang (karaoke). Unlike karaokes in Singapore, you do not book a room and pay upfront at the counter for a fixed duration but rather, go into any of the free booths and pay for a number of songs you want to sing. Usually, the prices are 1000 KRW for 2 songs, 5000 KRW for 12 songs and 10000 KRW for 26 songs, which is much cheaper than in Singapore! You will also be given a score for every song that you sing and it feels rewarding to receive a high score. It is also easy to change the tempo and the key of songs which allows for a more customisable and fun experience.
I was also able to enjoy world-class dance classes by famous dancers who have made choreographies for K-Pop artists. At the reputable 1 Million Dance Studio, they offer dance classes at various difficulty levels such that anyone can go and dance if they want to. I really enjoyed the choreographies I had learnt and the classes are memories that I will never forget.
I believe that these unique experiences can be enjoyed by anyone, solo or in a group, so I would recommend anyone going to South Korea to give them a shot!
