SEOULDAL (Seoul Moon Balloon)

SEOULDAL is a tethered helium balloon shaped like a full moon, anchored on the lawn of Yeouido Park and run by the city's tourism foundation since August 2024. Up to 20 people stand in the ring-shaped gondola, and the balloon rises straight up on its cable to about 130 meters, high enough to look across the Han River toward Nodeul Island and Namsan while the towers of Yeouido stand almost at eye level. A ride lasts about 15 minutes from boarding to landing, or around 30 minutes including the safety briefing. Daytime flights on clear days give the longest views, while evening flights show the lit bridges and the traffic streaming along the riverside roads. From the ground, the balloon itself glows after dark and makes a good photo from anywhere in the park. Because it uses non-flammable helium rather than a burner, it is calm and quiet in the air. Wind or rain can stop flights at short notice, so check the official update page on the day.
