Is Seoul Sky cheaper online than at the door?

Yes, generally — the cheapest platform we track (Klook, $18.49 as of Jul 23, 2026) runs below the official walk-up adult rate of ₩31,000 (~$21). Book ahead rather than buying at the counter.

Which floor is the glass floor — Sky Deck vs Sky Terrace?

The Sky Deck, at 478m, has the glass floor and holds the Guinness World Record for highest glass-floored observatory. The Sky Terrace, on the 120th floor, is a separate open-air outdoor deck without a glass floor.

Do I need to book a time slot in advance?

It's not always required, but sunset and evening slots are the most requested — reserve ahead for those rather than risking a sold-out window on arrival.

Seoul Sky vs N Seoul Tower — which view?

Different vantage points: Seoul Sky sits inside Lotte World Tower at 478m over the Jamsil/Han River side of the city, while N Seoul Tower is on Namsan mountain overlooking central Seoul from a lower absolute height but a hilltop position. Pick based on which part of the skyline you want — this guide covers Seoul Sky pricing only.

What You Actually Get: Seoul Sky's Floors

117–123F — the full observatory zone, reached by the Sky Shuttle, a double-deck elevator running at 600m/minute (about a 1-minute ride).
Sky Deck (478m) — the glass-floored section; Guinness World Record holder for highest glass floor in an observatory.
Sky Terrace (120F) — open-air outdoor deck.
Sky Friends Cafe (119F) — dessert cafe.
Premium lounge (123F) — the highest lounge in Seoul, wine and light bites.
On low-visibility days, an indoor Sky Theater screen substitutes for the outdoor view.

Best Time Slots & Booking Tips

Opening hours: 10:30–22:00 Sun–Thu, 10:30–23:00 Fri/Sat and public holidays; last ticketing is 1 hour before close (official).
Sunset and just-after-dark slots are the most requested times for the skyline view — book ahead for those windows rather than walking up.
The Fast Pass (₩62,000, on-site only) skips the regular line and needs no advance reservation — useful if you decide same-day, but at roughly 2–3x the price of the cheapest platform ticket, it's not worth it unless the standard line is genuinely long when you arrive.
Free parking up to 4 hours applies for Seoul Sky ticket-holders at the Lotte World Tower garage (official).

Getting There & What Else to Book

Seoul Sky is at 300 Olympic-ro, Songpa-gu — Jamsil area, a short walk from Jamsil Station on subway lines 2 and 8, and directly connected to the Lotte World Mall complex. If you're flying into Incheon, current tracked pricing for the AREX express train from the airport into Seoul, alongside this ticket, is below.

One planning note: general admission tickets from all three platforms above cover the same 117–123F observatory zone at the same access level — none of them include the Fast Pass skip-the-line perk, which is on-site-only regardless of where you book your standard ticket.
