Course Overview
Seosan is where vast west coast tidal flats meet rich historical heritage. This course starts at Ganwolam, a temple that becomes a sea island at high tide, passes through Seosan Birdland, and ends at Haemieupseong, a Catholic martyrdom site within Joseon-era fortress walls.
Ganwolam can only be reached on foot during low tide, making it a unique temple beautiful at both sunrise and sunset. Haemieupseong served as a military fortress during the Joseon Dynasty and carries the painful history of Catholic persecution.
