Lotte World Tower Seoul Sky sits on floors 117 to 123 of Korea's tallest building, a 555-meter skyscraper at 300 Olympic-ro in Songpa-gu, Seoul. The observation deck opens daily from 10:30 to 22:00 and charges KRW 27,000 for adult admission. Reaching the top takes about a minute in a double-decker elevator that ranks among the fastest in the world. Glass-floor sections on the lower observation level let you look straight down toward Jamsil, while floor-to-ceiling windows frame the Han River, Lotte World Mall, and the Tancheon stream on clear days.
How to buy Seoul Sky tickets and avoid the line
Tickets for Seoul Sky are sold at the box office on the B1 floor of Lotte World Tower Mall, but buying online in advance through the official Lotte World Tower site or platforms like Klook typically saves 10 to 15 minutes of queue time, especially on weekend afternoons. Adult admission runs KRW 27,000, with discounted rates for children, seniors, and Lotte Card holders. Printing or screenshotting your voucher speeds up the exchange counter, where staff swap it for a timed entry ticket.
Weekday mornings right after the 10:30 opening see the shortest lines, often under 10 minutes from ticket exchange to elevator boarding. Weekend crowds build steadily after 2:00 pm and peak again around sunset, when the wait for the elevator can stretch past 30 minutes. If you're combining Seoul Sky with Lotte World Mall shopping or the Lotte World Aquarium downstairs, buying a combo ticket at the B1 counter can shave a few thousand won off the total compared to purchasing separately.
Sky Terrace access on the 118th floor sometimes requires a separate timed slot printed on your ticket, so check the paper stub after exchange rather than assuming general admission covers it. Staff at the elevator gate on B1 scan tickets and direct groups into the Sky Shuttle, Korea's fastest double-decker elevator, which reaches the 120th floor in under a minute at speeds of 600 meters per minute.
Best time to visit Seoul Sky for views and sunset
Clear days are the deciding factor at Seoul Sky, and Seoul's air quality tends to be sharpest in autumn (October to November) and after rain in summer, when visibility toward the Han River and Bukhansan can stretch over 20 kilometers. Spring haze and yellow dust from March to May frequently soften the skyline, so if photography matters, check the Korea Meteorological Administration's visibility forecast the morning of your visit rather than relying on the general weather app icon.
Sunset slots between 6:00 and 7:30 pm from late spring through summer draw the thickest crowds, since the deck faces west-southwest toward the Lotte World Mall rooftop and the Han River bend near Jamsil Bridge. Arriving 45 minutes before sunset secures window space on the 118th floor before the rail fills in. Winter sunsets around 5:00 pm are quieter because the cold discourages casual walk-ins, making late afternoon one of the calmer windows for unobstructed photos.
Night visits after 9:00 pm show Seoul's skyline lit up, including the illuminated Jamsil Sports Complex and the Han River bridges glowing along their cables. The deck stays open until 22:00, and the last elevator up is typically called around 21:20, so plan your final ascent with a buffer if you want a full session at the top rather than a rushed 20 minutes.
What to expect on the Seoul Sky glass floor
The glass-floor section sits on the 118th floor and lets you stand directly above a sheer drop toward the plaza below, a feature that draws long photo lines on weekends, sometimes 15 to 20 minutes just for that spot. Staff limit the number of people standing on the panel at once, both for structural comfort and to keep photos clear of strangers, so patience during peak afternoon hours pays off. Socks are recommended over bare feet, and some visitors bring an extra pair specifically for this section.
Beyond the glass floor, the 117th floor houses a café and lounge area where you can sit with a drink while still facing floor-to-ceiling windows, a good option if you want views without standing the entire visit. The 123rd floor, known as the Sky Terrace, is Seoul's highest open-air observation point and opens seasonally, weather permitting, giving a rare outdoor perspective above the enclosed decks below.
Binocular stations placed along the windows on the 119th and 120th floors are free to use and help pick out landmarks like Namsan Tower to the northwest or the Olympic Park stadiums closer to the tower's base. Signage at each station labels major sightlines, which helps orient first-time visitors who might otherwise struggle to distinguish the Han River bridges from this height.
Seoul Sky vs N Seoul Tower: which observation deck to choose
Seoul Sky's 500-meter elevation dwarfs N Seoul Tower's roughly 236-meter combined mountain-and-tower height, giving Lotte World Tower a flatter, wider panorama that favors river and eastern Seoul views, while Namsan's perch delivers a more dramatic downtown skyline framed by hills. If your priority is spotting the Han River's full curve through Gangnam and Jamsil, Seoul Sky's vantage is harder to beat.
Ticket prices differ too: Seoul Sky costs KRW 27,000 for adults, while N Seoul Tower's observatory ticket is generally cheaper, closer to KRW 16,000, though you'll also pay for the cable car or bus to reach Namsan's summit. Seoul Sky's location inside Lotte World Tower Mall means easier access via Jamsil Station Line 2 and 8, with no separate hill transport required.
Crowd patterns also diverge: N Seoul Tower draws heavy evening date-night traffic and love-lock crowds around its terrace, while Seoul Sky's visitors skew toward families combining the deck with Lotte World Mall shopping or the aquarium. If you're short on time and staying near Gangnam or Jamsil, Seoul Sky's convenience wins; if you want a hillside walk and Namsan Park scenery built into the trip, N Seoul Tower suits that itinerary better.
Getting to Lotte World Tower Seoul Sky by subway
Jamsil Station on Seoul Subway Line 2 and Line 8 is the closest stop, connected directly to Lotte World Mall via underground passage, so you can walk from the platform to the B1 ticket counter without surfacing to street level. Exit 1 or 2 leads most directly into the mall's lower floors where the Seoul Sky elevator entrance is marked with tower signage.
From Gangnam Station, Line 2 gets you to Jamsil in about 15 minutes with no transfer, making Seoul Sky an easy half-day add-on if you're already exploring southern Seoul. From Myeongdong or central Seoul, expect a 30 to 35 minute ride with one transfer, typically switching to Line 2 at City Hall or a nearby interchange station.
Parking beneath Lotte World Tower is available for visitors arriving by car or taxi, though weekend rates and validation rules mean checking the mall's parking desk for the current discount tied to your Seoul Sky ticket. Taxis dropping off at the tower's main entrance on Olympic-ro avoid the mall's crowded underground lots entirely, which is useful if you're arriving with strollers or in a larger group.
