Route and time on site — Geumseoru to the four gates
The main entrance is Geumseoru, the west gate pavilion. Buy tickets there, follow the wall to Gongbukru on the north side above the Geumgang River, then the lotus pond, Manharu, Yeongeunsa, and Gwangbokru, and finish at Jinnamnu (south) and Yeongdongnu (east). One side of the wall path drops away; benches sit along the walk. There are slopes and stairs, so wear shoes with a low heel.
VisitKorea’s published stay is about 2 hours. That matches a photo walk of the 2,660 m wall (stone 1,925 m plus an eastern earth section of 735 m). Shorter “60 to 90 minutes” lap times you may see elsewhere are not the official figure—plan about 2 hours. The city does not publish minute-by-minute splits.
Gongsanseong is Historic Site No. 12 and joined the UNESCO Baekje Historic Areas in July 2015. It was the royal fortress of the Ungjin capital from 475 to 538. The ridge is about 110 m above sea level, with the Geumgang on the north. An estimated palace site sits on the west summit; the grounds cover about 200,000 ㎡ across Geumseong-dong and Sanseong-dong. Ssangsujeong is tied to the name Ssangsusanseong, used after King Injo stayed here during the Yi Gwal rebellion in 1624.

Getting there by car or city bus
For a car, set the nav to 280 Ungjin-ro (Geumseong-dong). The lot line is also listed as Geumseong-dong 65-3. Parking is free for both cars and buses. The city pages do not publish capacity or say whether you should park by Geumseoru or Gongbukru. On weekends, arrive early.
From Gongju intercity terminal, take city bus 101 or 125. Interval, fare, and the exact stop name are not on the official pages, so they are not listed here. Check a bus app or the terminal on the day you travel. Timed transfers from express buses or KTX are also absent from those pages—do not treat a guessed minute count as fact. There is no subway.
Wheelchair and stroller rental are not listed, and the main entrance may have a step. If you are visiting with a toddler or someone who has trouble with stairs, call +82-41-856-7700 before you go.
Costs — admission and the three-site ticket
Adults pay ₩3,000, or ₩2,500 in a group of 20 or more. Middle- and high-school students and soldiers pay ₩2,000 (group ₩1,500); elementary students pay ₩1,000 (group ₩500). A group of 20 is not free—it pays the discounted rate. Visitors aged 65 and over, people with disabilities, and preschoolers are admitted free under the city note; bring a senior card if you have one. Resident discounts conflict across city pages. The 10 scenic views page offers 50% off for Onnuri Gongju-citizen members, while a notes cell on the fee table mentions free entry mixed in with parking and closure text. Do not assume Gongju citizens are always free. Call +82-41-856-7700.
| Visitor | Individual | Group (20+) |
|---|---|---|
| Adult (ages 19–64) | ₩3,000 | ₩2,500 |
| Teen (middle/high school) and soldiers | ₩2,000 | ₩1,500 |
| Child (elementary) | ₩1,000 | ₩500 |
The combined ticket covers the Royal Tombs in Songsan-ri (King Muryeong), Gongsanseong, and Seokjangni Museum. Buy it at the first site you enter. Adults pay ₩6,000 (group ₩5,000). Teens pay ₩4,000 individual / ₩3,000 group; children pay ₩2,000 / ₩1,000. Three separate adult tickets cost ₩9,000, so the combined ticket saves ₩3,000. Two sites only cost ₩3,000 × 2 = ₩6,000, the same as the combined ticket—no saving.
| Adult | Amount |
|---|---|
| Gongsanseong only | ₩3,000 |
| Three sites, separate | ₩9,000 |
| Combined (tombs + fortress + Seokjangni) | ₩6,000 |
| Two sites only | ₩6,000 (same as combined) |
| Parking | ₩0 |
A simple day budget
Bus fares and meals are not published on the pages used here, so they stay out of the total. What is fixed on site is the ticket and parking. One adult at the fortress only: ₩3,000, parking ₩0. Two adults and one elementary child at the fortress only: 3,000 + 3,000 + 1,000 = ₩7,000. The same three people on combined tickets for all three sites: 6,000 × 2 + 2,000 = ₩14,000. Bought as separate tickets that would be 9,000 × 2 + 3,000 = ₩21,000. The ticket office is 041-840-2265. Follow on-site rules for card payment.
Tips and season — summer hours, winter hours, closed days
From March through October the gate is open 09:00–18:00, last admission 17:30. From November through February it is 09:00–17:00, last admission 16:30. After last admission you cannot enter, even with a ticket in hand. Do not plan a late-afternoon arrival. Closures are 1 January, Seollal day, and Chuseok day only—not the whole holiday stretch.
Heritage commentary runs 09:00–16:00 on the hour. Groups should book ahead at 010-5024-2421. Tourist information is +82-41-856-7700 (also listed as 041-856-3153 and 041-840-2266). Gate ceremonies change from year to year. If you want to see one, ask the city for that year’s times before you travel. This guide does not print a fixed ceremony time for them.
Spring and autumn show the wall and the river together. Summer has little shade; winter days end early, so buy tickets before 16:30. Rain or maintenance can close a section of the path. Check the Gongju city page and the phone line the morning you leave. Fees and hours can change.
