We highly recommend Yeum for Jeju island tours! This was our second time booking with him… and the first of three consecutive days on this trip. He tailored the tour to include the most enriching sites of the West side. He also added two of our requests— Hello Kitty Island and Osulloc Tea Museum. Yeum is knowledgeable, patient, and fun… there’s a reason we made sure to book him for our second Jeju trip!
