여행 The short answer
Pick N Seoul Tower if you want the classic Seoul view with the city wrapped around you, a cable-car ride and an easy evening near Myeongdong. Pick Seoul Sky if you want the highest deck in Korea, a glass floor and a sleek indoor visit that pairs with Seokchon Lake and Lotte World.
With only one evening, most first-time visitors are happiest at Namsan: the walk around the summit, the locks and the night view are free once you are up there, and the tower stays open late.

1Best for a first trip, sunset and night views
N Seoul Tower observatory
The 236.7 m tower sits on top of Namsan in the middle of Seoul, so downtown spreads out on every side, up to 50 km on a clear day. The trip up by cable car and the love-lock railings are half the fun. Klook sells an open-date mobile ticket, with packages that add the cable car.
-
2Best for the highest view and the glass floor
Seoul Sky, Lotte World Tower
The observatory fills floors 117 to 123 of Korea's tallest building (555 m). On 118F you stand on the Sky Deck glass floor, and 120F has an open-air terrace at 486 m. Klook sells Direct Entry and Fast Track tickets that you scan at the gate.

3Best if you're in Busan: ocean views
BUSAN X the SKY
Floors 98 to 100 of the 411.6 m LCT Landmark Tower, right on Haeundae Beach. Walk the glass-floored Shocking Bridge on 100F and step out onto the 99F Sky Garden. Unused Klook tickets can be cancelled free within their validity period.
N Seoul Tower: the view from the middle of the city
Namsan is a free forest park, and the tower rises from its summit. Ride Korea's first passenger cable car up from the Myeongdong side, or take Namsan circulation bus 01A or 01B. Cars and taxis can't drive to the top.
The 360-degree deck has digital telescopes, and after dark you can look for the 'star' that lit-up roads trace around Yongsan-daero. As of October 2026 the observatory is open 10:00–22:30 on weekdays and until 23:00 on weekends and holidays, with last entry 30 minutes before closing.
- Cable car lines can top an hour on weekends, so go up in the morning or take the bus.
- You can't bring your own food into the tower; the square by Palgakjeong is the picnic spot.
- Walk down on the stair-free Sky Forest Trail (about 30 minutes) for a quieter way back.
Seoul Sky: the highest deck in Korea
Lotte World Tower is 555 m and 123 floors, and the observatory takes up floors 117 to 123. The Sky Shuttle elevator runs from B2 to 117F. On 118F the Sky Deck is listed by Guinness World Records as the highest glass-floor observation deck, and 120F has the open-air Sky Terrace, which closes in bad weather.
As of October 2026 Seoul Sky opens at 10:30 and closes at 22:00 Sunday to Thursday and 23:00 on Fridays, Saturdays and the day before a public holiday. Ticket sales and entry end one hour before closing. The entrance is on the mall's B1 floor, from Jamsil Station (Lines 2 and 8).
- Changing the date is treated as a cancellation with a fee, and screenshots of tickets aren't accepted, so check the forecast first.
- Suitcases, strollers, outside food and bags larger than 43 × 25 × 22 cm can't go up; use the storage desk by the B1 ticket office.
- The Sky Bridge Tour, a guided walk 541 m up at the top of the tower, is closed from Nov 30, 2026 to Feb 28, 2027.
When to go
Go on a clear day and arrive about an hour before sunset, so you see the city by daylight, at dusk and lit up at night in one visit. Haze and fine dust can hide the far mountains, so check the forecast the morning you go.
Weekday mornings are quietest at both towers. Autumn is a good season on Namsan: the southern walking path usually turns color from late October to early November.
Heading to Busan? BUSAN X the SKY
At the east end of Haeundae Beach, the LCT Landmark Tower is Korea's second-tallest building. Its observatory on floors 98 to 100 looks straight down the beach and out to sea, and it is open daily 10:00–21:00 (on-site ticket sales end at 20:30).
Its tickets are for a printed date and time with no re-entry, so check the weather before you buy. Pair it with the Haeundae Blueline Park Sky Capsule along the coast.
FAQ
Which is higher, N Seoul Tower or Seoul Sky?
Seoul Sky. Its decks are on floors 117 to 123 of the 555 m Lotte World Tower, with an outdoor terrace at 486 m. N Seoul Tower itself is 236.7 m, but it stands on top of Namsan, so its view is still high and sits right in the center of the city.
Do I need to book ahead?
Not always, but it helps. Seoul Sky tickets are for a set time slot, so booking ahead holds a sunset slot, while the Klook N Seoul Tower ticket is open-date. Booking ahead also lets you skip the ticket counter. Read each ticket's refund rules first, since many can't be cancelled.
Can I visit both in one day?
Yes. Namsan is in central Seoul and Lotte World Tower is in Jamsil in the southeast, under an hour apart by subway. A good plan is Seoul Sky in the afternoon and Namsan for sunset and the night view, since the tower and the summit stay open later.
Is N Seoul Tower worth it if I only walk up to the top?
Yes. Namsan Park, the trails, the love locks and Palgakjeong pavilion are all free, and the summit plaza already has a wide view. The paid observatory adds the full 360-degree view from higher up and the telescopes.
