MapleStory 'Orange Mushroom' giant balloon exhibition at Seokchon Lake (Jamsil) — May 22 to June 21, 2026
Visited Seokchon Lake(East Lake side) in Jamsil today and there's a fun new free attraction worth a stop if you're in the area, especially for MapleStory fans or anyone traveling with kids.
Songpa-gu and Nexon set up a MapleStory exhibition on the lake to mark the game's 23rd anniversary(Maple Attack). The centerpiece is a giant Orange Mushroom art balloon floating on the water with several Slime balloons around it.
Practical info for travelers:
- Dates: May 22-June 21, 2026
- Hours: 10:00-22:00 daily, Night lighting turns on around 19:00, so it looks nice after dark too.
- Cost: Free to view from the lakeside walking path.
- Getting there: Seokchon Lake is right next to Jamsil Station(Line 2&8) and Lotte World/Lotte World Mall, so It's easy to combine with those.
There are also some side activities during the run(Pink Bean stamp rally, an AR 'treasure mushroom hunt', and bubbles released on the hour).Some prize events need a receipt from nearby restaurants/cafes, which is more aimed at locals, but the balloons themselves are open to everyone.
My take: I went around Saturday lunchtime. There were a decent number of people taking photos and joining the activities, but it wasnt packed at all-easy to walk right up to the railing and get clear shots without waiting. So if you're worried about crowds, a weekend midday visit still felt pretty relaxed.
If you're already heading to Lotte World or Jamsil, It's an easy 15-20min detour worth doing before June 21!
