Seoul has two main observation decks worth visiting: N Seoul Tower on Namsan Mountain (479m above sea level) and Seoul Sky on Lotte World Tower (555m above ground). Here is an honest comparison so you can decide which one fits your trip, or whether both are worth it.
The Quick Answer: For the city panorama and the most complete view of Seoul, Seoul Sky on Lotte World Tower. For the most atmospheric visit experience and the best value: N Seoul Tower. For a first-time visitor, choose Lotte World Tower Seoul Sky for the view, or N Seoul Tower if you prefer character and a lower cost.
N Seoul Tower (Namsan Tower)
Height: 236m above ground (479m above sea level, sitting on top of Namsan Mountain).
Observatory ticket: 21,000 won for adults, 15,000 won for children.
Access: Cable car (14,000 won return) or a 20 to 30-minute hike from Myeongdong or Itaewon. The approach through Namsan Park and the cable car ride are part of the experience.
What makes it distinctive: The mountain setting means you see Seoul from a forested hillside rather than from a skyscraper. The surrounding Namsan Park is beautiful in every season. The love lock fence below the tower is one of Seoul’s most-visited outdoor gathering spots. The observatory feels integrated into the city landscape rather than above it.
Best for: Romantic visits, daytime panoramas (particularly looking south toward the Han River), visitors who want to combine the tower with a Namsan Park walk, and those wanting a lower ticket price.
Full details in the Namsan Seoul Tower guide.
Lotte World Tower Seoul Sky
Height: 500m above ground (the observation deck). Tower total height 555m.
Observatory ticket: 29,000 won for adults, 22,000 won for children.
Access: Jamsil Station on Lines 2 and 8, direct underground connection to the tower. The most straightforward access to any Seoul observation deck.
What makes it distinctive: At 500 metres, the view is genuinely broader than any other viewpoint in Korea. The Han River curves visibly below, the entire Gangnam and Jamsil districts are laid out, and on clear days, the mountains north of Seoul appear as a distant ridge. The glass-floored sky observatory section is the most vertiginous floor-staring experience in the country.
Best for: Night visits (the city illumination from 500m is the finest in Seoul), first-time visitors who want the maximum view, visits combined with Lotte World theme park next door.

Side-by-Side Comparison
View quality: Lotte World Tower wins on raw breadth. N Seoul Tower wins on integration with the natural landscape.
Value for money: N Seoul Tower at 21,000 won versus Seoul Sky at 29,000 won. N Seoul Tower is the better value.
Accessibility: Lotte World Tower win—subway direct connection. N Seoul Tower can be reached by cable car or by hiking.
Experience: N Seoul Tower has more character. The park, the cable car, the love lock fence, and the mountain setting give it an atmosphere that a skyscraper deck lacks.
Night visit: Both are excellent at night. The Han River from Lotte World Tower at night is spectacular. The city below N Seoul Tower at night, with the Namsan forest visible as a dark island in a sea of neon, is also striking.
Should You Do Both?
If time allows, yes. They are genuinely different experiences, and the combined entry cost (about 50,000 won) is modest relative to the overall cost of the Seoul trip. Visit N Seoul Tower during the day or at sunset, and Seoul Sky in the evening, or vice versa.
