You can visit the DMZ as a day trip from Seoul. Most people take a bus tour that picks up at hotels, Myeong-dong, or Hongdae. A standard DMZ tour takes 5 to 8 hours. JSA (Joint Security Area, Panmunjom) tours are fully suspended right now, so you can only join DMZ tours that skip the JSA.
The DMZ (Demilitarized Zone) is a buffer zone about 4 km wide. It was created under the armistice agreement of July 27, 1953, when each side pulled back 2 km from the military demarcation line.

Standard DMZ Tour: 5 to 8 Hours
The standard DMZ tour is the basic day trip from Seoul. It takes 5 to 8 hours and visits the Third Tunnel and Dora Observatory. The route runs in this order: Imjingak, the Third Tunnel, Dora Observatory, and Dora Station.

From Dora Observatory, you can see the area north of the military demarcation line.

JSA Tours: Fully Suspended
JSA tours are currently fully suspended. The JSA tour booking page on Trazy says "currently unavailable due to government regulations" at the top. It also says the suspension may continue without advance notice. The JSA tour once listed on VIP Travel is not a valid product either.
JSA tours have been suspended on and off since 2023. The Ministry of Unification's Panmunjom visits also stopped on December 1, 2023. They resumed on May 16, 2025, as special tours for policy-related groups. If you are a general traveler, choose a standard DMZ tour that does not include the JSA.

DMZ Train: Second and Fourth Fridays
The Korail DMZ train is called the Peace Train (평화이음 열차). It makes one round trip a day from Seoul Station to Dora Station on the second and fourth Fridays of the month. Its first run was on April 24. The train enters a Civilian Control Zone, so you need to book ahead and bring photo ID. Reservations are made on the Korail and Korail Tourism Development websites.
KoreaToDo lists this train as "currently suspended" and describes the fare as free. The same page says the Gyeongui Line course from Yongsan to Dora Station includes the Third Tunnel, Dora Observatory, Dora Station, and Peace Park. It also says the JSA is not part of the train tour. It adds that tourist sites near the DMZ can only be visited on group tours.
