Sangseung Observation Post is a popular security tourism destination, providing a unique vantage point to observe enemy activities near the Demilitarized Zone (DMZ). Due to its location within the DMZ, the actual First Tunnel is inaccessible; however, a full-size model is available at the nearby Sangseung Observation Post. Visitors are required to apply seven days in advance and present identification at the post for access.
