My 7 and 10 year old absolutely loved this experience. My 10-year did the dolphin swimming and my 7-year old did the dolphin training. My husband and I have done dolphin encounters before, but not like this--you get your money's worth as they give you plenty of time with the dolphins! Swimming with the dolphins at Marine Park Jeju has probably been the highlight of our time on Jeju Island. We were impressed with how this place takes care of their dolphins. There was even a moment where one of the dolphins didn’t want to play with my son at the time and they didn’t force her into anything and just had us wait until she was ready to play again. Korea is currently the only country in the world that has seen aquarium dolphins released back into nature successfully reproduce. We HIGHLY recommend this excursion!!
