1. What & Where: N Seoul Tower at a Glance

N Seoul Tower (also called Namsan Tower) is a 236-meter communication and observation tower on top of Namsan in central Seoul. It broadcasts TV and radio signals and offers multiple observation levels, restaurants, and photo zones. Expect 360-degree city views and illuminated night scenes.

2. Tower Colors & Air Quality

N Seoul Tower uses night lighting as a public air-quality signal. In clean air the tower shines sky blue. As conditions worsen you will see green or yellow. When pollution is high or an advisory is issued the tower turns red. It is an easy visual cue for locals and visitors across the city.

Note: the exact thresholds are based on city guidance for particulate matter. If you see sky blue, conditions are generally good. If you see red, consider limiting outdoor time and using a mask if you are sensitive.

3. What To See & Do

Observatory decks. Wraparound views with indoor and terrace photo spots. Time your visit for sunset, then stay for the grid of city lights.

Locks of Love. The iconic padlock terraces around the plaza are a classic couple photo stop.

Dining with a view. The tower hosts options from casual dining to a fine-dining restaurant at the top. Reserve for prime evening windows and city lights.

Photo zones and exhibitions. Expect seasonal installations and themed areas around the plaza and decks.

4. Getting There, Hours & Tickets

Namsan Cable Car. The simplest way up from the Myeong-dong area. Operations can extend into late evening and may pause for weather or inspection. Lines are shorter earlier in the day and after the dinner rush.

On foot or by shuttle/bus. Scenic park trails climb the hill. Local shuttle and city buses stop near the tower plaza. Wear supportive shoes if you plan to walk down.

Tickets and hours. Ticket types and hours change seasonally. As a rule of thumb, the observatory runs from morning into late evening, with last entry before closing. Always check the official site on the day you visit.

5. Easy Add-Ons Around Namsan

Namsan Park. Forested paths, city-wall sections, and elevated viewpoints loop around the hill. It is easy to fit a 30 to 60 minute walk before or after the tower.

Myeong-dong and Namdaemun. Shopping streets, street food, and classic markets are a short walk or bus ride from the base station.

Namsangol Hanok Village. Traditional houses, craft demos, and calm courtyards sit on the north side of the mountain and pair well with a daytime tower visit.
