The Lotte World Tower, which houses the observatory, was designed to resemble a traditional Korean porcelain brush.
The Sky Shuttle elevator uses double-deck technology to transport two groups simultaneously while displaying panoramic video on its interior walls during the ascent.
During optimal weather conditions, visibility from the observation deck extends up to 40 kilometers.
The structure's exterior facade is comprised of 42,000 glass panels, all of which are uniquely shaped.
The building is designed to withstand earthquakes of up to a magnitude of 9.0 and wind gusts of up to 80 meters per second.
Seoul Sky is an observation deck located on the top floors of the Lotte World Tower, the tallest building in South Korea and the sixth-tallest in the world. It spans floors 117 to 123, reaching an altitude of 555 meters above ground level. The facility features a glass-floored section known as the Sky Deck, which is listed by Guinness World Records as the highest glass-floor observation deck globally. High-speed double-deck elevators, known as Sky Shuttles, transport visitors to the top in approximately one minute. The observation area offers 360-degree panoramic views of the entire Seoul metropolitan area, including the Han River. Guests can access a premium lounge on the 123rd floor for beverages and snacks. The venue incorporates multimedia exhibits detailing the history and construction of the tower.
The 118th-floor Sky Deck provides the most dramatic perspective looking directly down at the ground.
Check the real-time visibility index on the official website before heading to the tower to ensure clouds or smog do not obscure the view.
Visit during the late afternoon to experience the city transition from daylight to the evening light show.
Book your timed-entry reservation online in advance to bypass long ticket office queues.
Avoid visiting on days with high particulate matter (yellow dust) or thick fog, as visibility will be significantly limited.
Refrain from leaning excessively on glass railings and remain mindful of other guests when using the glass-floor area.
