Gonae Port, located in Aewol-eup, Jeju City, is a small port that you pass while driving along the Aewol-eup coastal road, where you can enjoy the emerald Jeju sea. This place, filled with the leisurely and quiet atmosphere of a fishing village, is visited by many tourists due to its clear and clean sea and the 16 Olle Trail courses. On the long breakwater facing the sea, you can often see people trying to take pictures as well as people who enjoy fishing as a hobby while spreading out their chairs. The water is so clear that if you look into the sea, you can directly see the fish swimming around. It is the start of Jeju Olle Trail Course 16 and the end point of Course 15.
