KTO's Durunubi maps the Boryeong–Hongseong section of the Seohaerang Trail to courses 59~63, emphasizing western coastal paths and seaside scenery. The courses do not all share the same distance or difficulty.

[Local planning] Check each course map for any tide-dependent crossings.

Check the official detailed map for the exact start, end, distance, difficulty and route. Verify tides, restrictions, accommodation, facilities and local transit separately.
