Udo Cheonjin Port is the passenger harbor where boats from Seongsan Port on Jeju arrive on Udo. Electric bicycle and electric cart rental shops cluster around the entrance, and renting one takes about 1 hour 30 minutes to circle Udo's coastline. There is no separate ticket office and no building to wait in, with only a simple toilet and snack stalls and restaurants nearby. Right after arrival, touts for vehicle rentals make the area crowded.
