63 SkyPicnic (63 Building Observatory)

The golden 63 Building has been a Seoul landmark since 1985, and its 60th-floor observatory, about 250 meters up, reopened on June 4, 2026 as 63 SkyPicnic after the old 63 Art gallery closed in 2024. The redesign leans on media art: the main deck is lined with hundreds of mirrors, so the Han River, the Yeouido towers, Namsan and the Jamsil skyline repeat endlessly around you, and screens lower and rise to switch between projected scenes and the real view. There is a five-sided projection theater called Sky Voyage Theater, a Sky Stage filled with rainbow-colored balls, and themed hologram exhibits that change with the seasons. The biggest draw is the outdoor rooftop on the 63rd floor, the former helipad, which gives a 360-degree open-air view of the river; it is the only open rooftop among Seoul's major observatories and faces the Han River sunset. A Starbucks inside is open only to ticket holders, so you can sit with a coffee and the view after your visit. Allow about one to two hours.
