We went there in May 2015, we participated in Jeju Island Golden City Bus Tour (very bad!), we only went to play for 1 hour in total! The exhibition hall is spectacular, the attraction itself is great, the atmosphere is very good! The exhibition hall tickets are not expensive, I remember about 1,000 won. The cafe there is a very high charge though. The museum is in a remote location but it is easy to find. We thoroughly enjoyed the experience. The exhibitions here are all impressive. It’s a relatively small museum, but it’s the highlight of my day.
