Seosan City’s official walking-route guide lists Gudo Beommeori Trail A: 24 km as 24 km. A long loop starting and ending at Palbongsan Yanggil-ri Parking Area. It connects Solgam Reservoir, Gudo Port, Jubeokbae Viewpoint, Palbong Tidal-flat Experience Area and Hodeok reclamation land around Garorim Bay.
Before you set out: At 24 km this is a long route, distinct from the shorter B loop. Check tides and tidal-flat restrictions and allow enough daylight. Consult the official map for current access, carry water and a charged phone, and plan your return. Recorded GPS distances may differ.
