One lake, two different trails
In Goesan, Chungcheongbuk-do, the similarly named Sanmagi Old Trail and Sanmagi Lakeside Trail offer views of Goesan Lake, but the county presents them as separate routes. This distinction matters most when planning a winter visit.
The Old Trail: about 4 km of restored village history
The county describes the Old Trail as a roughly 4 km former route linking Saorang village and Sanmagi village. Sections use wooden decking to follow wooded hillsides above the water. Beyond the scenery, the appeal is the story of a local path restored with an effort to limit environmental damage.
The Lakeside Trail: 2.3 km with its own timetable
The separate 2.3 km Lakeside Trail runs from Chadolbawi Dock via the Goesan Dam pedestrian bridge toward Hwanbyeokjeong. The county lists winter hours of 10:00–17:00. On weekdays, only the dock-to-bridge section is open; on weekends and public holidays it lists the full route. The Lakeside Trail closes in January and February. These rules must not be assumed to apply to the entire 4 km Old Trail.
Save the right starting point
For the Old Trail parking area, the county gives 517 Saeun-ri, Chilseong-myeon, Goesan-gun. The Lakeside Trail has a separate location near Chadolbawi Dock (San 41-2, Saeun-ri). Published parking charges are ₩3,000 for small/medium vehicles and ₩7,000 for large vehicles, subject to change. The county also provides bus timetables, but live operation and connections need checking.
A better November walk
Choose between following a restored old village route and exploring the newer lakeside walkway. Confirm weather closures, the accessible section and any boat services independently. The same lake can tell a different story from each path.
