Ocheon Port is located in the northern part of Boryeong-si, where the Hwanghae Sea and Gwangcheoncheon Stream meet. It was once an important regional administrative center during the Joseon dynasty (1392-1897). Today, the port still retains its function, and visitors can explore and purchase various seafood caught in the Hwanghae Sea at the market. Ocheon Port Ferry Terminal operates ferry services to nearby islands such as Woldo Island and Yukdo Island.
