If you're a huge BTS fan or part of the BTS Army, then the Iryeong Station should be one of the places on your list. It is one of the film locations of BTS's "Spring Day". It's located not too far away from Seoul and it makes for a perfect day trip out to see the outskirts of Seoul. Located in Yangju City, this place is less than an hour away from Seoul Station. It's considered a decommissioned train station since 2004 when passenger trains were suspended. However, one thing to note is that they are still open to handle railroad crossings. For now, military-only trains still operate and stop at this station on certain occasions so when you're there please be careful. Stay on the platform at all times and be sure to check for incoming trains in the distance.
