The trip to Jeju

In this summer break,I went to Jeju. It was the third time I visit there. The first time I visited,I was a middle school student. I just remember I walked too much along the shore about 3hours. The second one was a school trip when I was a highschool student. On this trip,I experienced a lot. I climb up to mountain Halla which is the highest in Jeju island. It was challenging,but I felt achievemnet. When I visited Jeju this time,I took a lot of rests. I enjoyed delicious food especially seafood. I swam in the water at the beautiful and quiet beach. It was wonderful time of this year. I would like to go there again.
