Gongju's Royal Downtown Route 3 is the shortest of the three, about 1.6 km and 25 minutes. The official route map links Gongsanseong Fortress to Gomanaru via the riverside connector and Jemincheon Stream, with Art Centre Goma noted as a nearby optional stop. Food options around Baekmi village, views of the Geumgang Bridge completed in 1933, and the riverside pine grove near Gomanaru make distinct stops. Check current bridge access and path conditions locally.
