I was in Jeju for a conference and wanted to take a day to see some of the sites of the island. I contacted Victor to ask if he would be able to accommodate my request for a one-day tour. He was very willing to have me join the group (and thank you to the group) for just one day. He picked me up at my hotel in the morning and then I joined the rest of the group at their small hotel. Although I was at the hotel for only a short time, it looked modern, peaceful and a great place to stay for some respite. His prices are reasonable, he speaks English, German and Korean which he flowed through all day long with ease. Lunch at the small local restaurant was great. I felt like I was getting a very authentic experience.  All entry fees were included in the tour price which was very helpful. I recommend Victor and Jejueco for your Jeju travel plans.
