Samnamgil is a walking path for dogs in Gosaek-dong, Suwon. It passes under the old Suin Line railway bridge and connects to Suwoncheon and Hwangguji Stream, with a bicycle road running alongside. Until 1995, narrow-gauge Suin Line trains ran along this route, and part of the path looks toward Suwon Station. The lower section of Seoho Stream is less well maintained.
