Lydia was a wonderful guide for my day trip around the east side of Jeju. I had a few things I wanted to see and was open to her suggestions for others. She was very helpful explaining about what we could fit into one day and what we couldn't. I was not aware how big Jeju really is and she was able to help put together an iterinary that covered the most important sights I wanted to see. She was friendly and knowledgeable about the island. I would highly recommend Lydia!
