Getting back

For what is actually running tonight, the map apps are the accurate answer. Below is what they cannot tell you.

Nearest station

Munhak Stadium Station 문학경기장역 (Incheon Line 1)

Last train, weekdays 인천1호선 24:18 → 검단호수공원 · 24:52 → 송도달빛축제공원· weekend 인천1호선 24:18 → 검단호수공원 · 24:52 → 송도달빛축제공원

Incheon Line 1 is a separate line from the Seoul Metro. Both terminus stations—Geomdan Lake Park and Songdo Moonlight Festival Park—are in Incheon. To return to Seoul, you must transfer at Bupyeong Station (Line 1) or Gyeyang Station (Airport Railroad). When calculating return time, add the transfer time. The last train toward Geomdan Lake Park passes through both stations. The departure times are the same on weekdays and holidays.

These times come from the published timetable. Trains after midnight are written as 24:00 and later, exactly as the platform boards write them. Holidays and special schedules change them, so confirm once more in a map app on the day.

The last train from this venue does not reach central Seoul

If you plan to take a taxi, budget for it in advance. The ride-hailing apps usually want a Korean phone number, and the front of a venue just after a show is the hardest place in the city to find a cab.

Near here, after the show

Late food Cafés Pubs & bars Clubs

Clubs fill up after 10pm and run until dawn. Bring your passport — the door will check ID. Entry policies vary from place to place, so it is worth having more than one in mind.
Last subways vary by line but generally go around midnight. Shows usually end between 10 and 11pm, so leaving promptly you will normally make it — it is the merch queue and the photos that cost people the train.
After the subway stops, night buses numbered with an N run until roughly 3–4am. Your T-money card works on them, and the routes show up in any map app.
The street outside a venue at closing time is the hardest place in the city to find a taxi, and the hailing apps usually want a Korean phone number. Walking five minutes to a main road is normally faster than waiting.
Look up your way back before the show rather than after it. Afterwards you will be in a crowd, on the move, with no room to study a screen.
