1. Haemi Eupseong Festival: 3 Things to Know Before You Go

Festival Overview & Historical Background

The Seosan Haemi Eupseong Festival is the 23rd edition of one of Chungnam Province’s most celebrated cultural events, hosted by Seosan City. The venue — Haemi Eupseong (해미읍성) — is a remarkably well-preserved Joseon Dynasty walled town (eupseong) built in 1421 under King Taejong. It served as the headquarters of the Chungcheong Province military command and is also one of Korea’s most significant Catholic martyrdom sites, listed on UNESCO’s Tentative World Heritage List. For foreign visitors, this is a rare chance to step inside an intact Joseon fortress that remains an active historical monument. The 2026 theme, “HAEMI UNIVERSE,” opens a portal through 600 years of history, fusing Joseon heritage with modern spectacle. According to official announcements, the festival runs October 9–11, 2026, at Haemi Eupseong, 143 Nammun 2-ro, Haemi-myeon, Seosan-si. Admission is completely free.

2026 Performance Lineup

The 2026 festival lineup is the strongest in its 23-year history. Jang Yoon-jeong — Korea’s beloved trot (트로트, a traditional Korean pop genre) queen, known for her powerful vocal performances and national popularity — headlines the opening ceremony on October 9 (Friday) at 7:00 PM. DinDin, a popular Korean hip-hop artist, comedian, and variety show personality, also performs during the festival weekend. On October 10 (Saturday) at 1:00 PM, the Black Eagles (대한민국 공군 블랙이글스) — the Republic of Korea Air Force’s elite aerobatic demonstration team, flying 8 T-50B Golden Eagle jets — perform directly above Haemi Eupseong in a breathtaking aerial display. All concerts and shows are free to attend without any separate ticket.

1,000-Drone Light Show: What to Expect

The highlight of every evening at the 2026 Haemi Eupseong Festival is the synchronized flight of 1,000 drones illuminating the night sky above the ancient walls. According to the official schedule, the drone show runs all three nights: Friday at 7:30 PM, and Saturday and Sunday at 6:30 PM and 8:30 PM (two shows per night on weekends). One thousand drones form dynamic shapes and patterns in formation — one of the largest drone light shows in South Korea. The best viewing spot is the wide open plaza outside the fortress walls (성벽 외부 광장 — pronounced: seongbyeok oebu gwangjang). Arrive at least one hour before showtime to claim a good position.

Festival accommodation along the Seosan corridor books up quickly around the October 9–11 dates. We recommend using Agoda or Booking.com to compare properties in Seosan city center or Cheonan — a nearby transit hub roughly 60–90 minutes from Haemi by bus. Booking 2–3 weeks in advance is strongly advised, as this is the largest annual event in Chungnam Province.

2. Dates, Venue & How to Get There from Seoul

Opening Ceremony & Main Stage Area

The opening ceremony takes place on Friday, October 9, 2026, at 7:00 PM in the Haemi Eupseong grounds. Jang Yoon-jeong’s opening performance flows directly into the first 1,000-drone show at 7:30 PM — making opening night the most action-packed of the three days. The main stage sits inside the fortress courtyard, where Joseon-era architecture provides an extraordinary backdrop for contemporary performances. English signage may be limited inside the venue; look for guidance from volunteer staff or use the Korea Travel Helpline (1330), which offers 24/7 English assistance.

Black Eagles Air Show Zone (Saturday, October 10 at 1:00 PM)

The Black Eagles aerobatic show takes place on Saturday, October 10 at 1:00 PM, with the jets performing directly above Haemi Eupseong. The optimal viewing zone is the wide open area outside and around the fortress walls, where the full sky is visible. The show runs approximately 40–60 minutes, and safety-designated viewing zones will be marked on the day — follow staff instructions. A smart plan: arrive at Haemi Eupseong by 10:00–10:30 AM, spend the morning exploring the fortress interiors (free), then secure your air show spot by 12:00 PM.

How to Get There from Seoul / Incheon Airport

From Seoul (Gangnam / Central City Terminal): Take an intercity express bus to Seosan Bus Terminal (서산 시외버스터미널). Buses depart roughly every 20–30 minutes from Central City Terminal (강남) with a journey time of approximately 1 hour 50 minutes. From Seosan terminal, take a local city bus toward Haemi Eupseong or hire a taxi (approx. 10–15 min, around 8,000–12,000 KRW). From Seoul Nambu Terminal: Direct buses to Haemi depart roughly every 50–80 minutes (approx. 1 hr 50 min). From Incheon Airport: Take the AREX (Airport Railroad Express) or Airport Limousine Bus to Seoul, then transfer to a bus for Seosan at Central City Terminal. Total journey: approximately 3 hours. Note that a KTX connection to Haemi is not available — the express bus is the primary option. During the festival weekend, Seosan City may operate shuttle buses from Seosan terminal to the festival site; confirm in advance via the 1330 Korea Tourism Helpline.

3. Tickets & Entry: 4 Steps for Foreign Visitors

Step 1: Confirm Admission (Spoiler: It’s Free)

The 2026 Seosan Haemi Eupseong Festival has no admission fee. No pre-booking, no ticket app, no online reservation is required. Simply walk through the main gates — the South Gate (남문, Nammun) or West Gate (서문, Seomun) — and enjoy. All major programs, including the opening concert, Black Eagles air show, and nightly drone light show, are included at no cost. Some hands-on cultural experience booths inside the fortress may have small separate fees; look for signage at each activity station. For the latest updates, check the official VisitKorea English page or contact the Korea Tourism Helpline at 1330.

Step 2: Choose Your Transport & Plan Arrival

By private car: Enter “143 Nammun 2-ro, Haemi-myeon, Seosan-si” (충남 서산시 해미면 남문2로 143) into any Korean navigation app (Kakao Map works well). By public transport: Travel by express bus from Seoul’s Central City Terminal (센트럴시티터미널) or Nambu Terminal (남부터미널) to Seosan Bus Terminal, then transfer to a local bus or taxi to Haemi Eupseong. Most vendors at the festival accept credit cards; however, smaller experience booths and food stalls may be cash (KRW) only — it is worth carrying some Korean won.

Step 3: Claim Your Drone Show Spot

The prime viewing area for the 1,000-drone show is the open plaza outside the fortress walls, near the North Gate direction. Arrive at least one hour before showtime to secure a good spot: Friday at 7:30 PM, Saturday and Sunday at 6:30 PM and 8:30 PM. Bring a blanket or folding chair if possible, as the ground can be hard. Evening temperatures in October in Seosan can drop to around 10°C (50°F) — dress warmly. For photos, use smartphone night mode or a wide-angle lens to capture the full drone formation. Foreign visitors with valid passports are eligible to attend all programs.

Step 4: Position for the Black Eagles Air Show

For the Black Eagles aerobatic display on Saturday, October 10 at 1:00 PM, stand in the open area outside the fortress walls or in the large parking area nearby where the full sky is unobstructed. Avoid standing too close to the fortress walls, as they may block your view. Arrive by 11:00 AM, use the morning to explore the fortress interior, and move to your air show viewing spot by 12:30 PM. Security staff will guide visitors to designated safe viewing zones on the day.

4. Where to Eat & Stay Near Haemi Eupseong

Ganwoldo Oysters & Local Seosan Food

Seosan is famous for two local delicacies: Ganwoldo oysters (간월도 굴) from the tidal flats of Ganwoldo Island, and Seosan six-clove garlic (서산 6쪽마늘). Ganwoldo Island is located about 20–30 minutes by car from Haemi Eupseong, making it a perfect pre- or post-festival food stop. Look for charcoal-grilled oysters (굴구이 — pronounced: gul-gu-i) and oyster rice (굴밥 — gul-bap) at restaurants near Ganwoldo. During the festival, food vendor stalls inside and around the fortress grounds serve local Seosan specialties — a great way to sample regional flavors. Credit cards are accepted at most sit-down restaurants; cash may be needed at smaller stalls.

Accommodation Options Near the Festival

For accommodation, Seosan city center offers the most convenient access to Haemi Eupseong, with a range of business hotels and guesthouses. Search “Seosan hotel” or “Cheonan hotel” on Agoda or Booking.com for English-language booking options with international card payment. Budget options typically run from approximately 40,000–90,000 KRW per night (approx. $29–$66 USD). Cheonan — about 60–90 minutes from Haemi by bus — offers a wider selection of international-style hotels near Cheonan-Asan Station (KTX-connected to Seoul in ~50 min). Book at least 2–3 weeks in advance for the October 9–11 festival weekend.

Recommended Day-Trip Itinerary

The optimal one-day itinerary for October 10: Morning — explore the Haemi Eupseong fortress interiors (walls, government office, prison ruins, Catholic martyrdom site); Midday (1:00 PM) — Black Eagles air show; Afternoon — lunch at Ganwoldo oyster restaurants (20–30 min away); Evening (6:30 PM or 8:30 PM) — return for the 1,000-drone light show. From Seoul by bus, plan to depart by 8:00–9:00 AM to arrive comfortably by 11:00 AM. Check bus return times to Seoul in advance — the last buses may depart Seosan in the late evening.

5. Haemi Eupseong Festival vs. Other Korean Historical Festivals

South Korea hosts many historical and cultural festivals each autumn, but the Seosan Haemi Eupseong Festival stands out for its unique combination of Joseon-era heritage and modern spectacle. Here’s how it compares:

6. 5 Tips for Foreign Visitors

Tip 1: Visit on Opening Day (Friday, October 9)

The weekend days (October 10–11) will draw significantly larger crowds than opening day on Friday. Visiting on October 9 lets you experience Jang Yoon-jeong’s opening performance and the first drone show in a relatively relaxed setting, with far less competition for parking and food stalls. However, if the Black Eagles air show is your top priority, Saturday (October 10) is non-negotiable — the aerobatic display only happens that day. For Saturday visits, aim to arrive before 10:00 AM to secure parking and a good spot for the 1:00 PM air show.

Tip 2: Best Spots for the Drone Show

The best positions for the 1,000-drone light show are the open plaza outside the fortress walls and the wide open area near the North Gate (북문 방향). Arrive at least one hour before the scheduled showtime. For the later weekend shows (8:30 PM), temperatures in Seosan in October can feel close to 10°C (50°F) — bring a warm jacket or a blanket. To capture the drone formations, use your smartphone’s night mode or a camera with manual long-exposure settings; a small tripod will help significantly.

Tip 3: Air Show Viewing Strategy

The Black Eagles air show (Saturday, October 10 at 1:00 PM) lasts approximately 40–60 minutes and covers a wide expanse of sky. Position yourself in an open area away from the fortress walls — standing too close will partially block your view. Safety-designated viewing zones will be marked by staff on the day. A useful Korean phrase: “에어쇼 관람 구역이 어디예요?” (Eo-eo-syo gwal-lam gu-yeok-i eo-di-e-yo?) — “Where is the air show viewing area?” Arrive by 11:00 AM, explore the fortress, and move to your air show spot by 12:30 PM.

Tip 4: Transport & Parking Plan

On the weekend (October 10–11), parking at and near Haemi Eupseong fills up early — target arrival before 9:00 AM. Seosan City may operate shuttle buses from temporary overflow parking lots to the festival site; check the 1330 Korea Tourism Helpline (English available 24/7) for the latest shuttle information before you go. For those using public transport, local city buses from Seosan Bus Terminal run to Haemi Eupseong, but headways can be long — supplement with a taxi via Kakao T app if needed. If returning to Seoul by bus, check the last departure time from Seosan in advance.

Tip 5: Explore Haemi Eupseong’s History First

Before the performances begin, dedicate 1–2 hours to exploring the fortress itself. Haemi Eupseong (해미읍성 — pronounced: hae-mi eup-seong) contains the original Joseon government office (동헌, dongheon), residential quarters (내아, nae-a), prison ruins (형옥, hyeong-ok), and a significant Catholic martyrdom site — the location where thousands of Korean Catholics were executed during the 19th century persecutions. For Catholic travelers, this site holds deep historical and spiritual significance, as Haemi Eupseong is on UNESCO’s Tentative World Heritage List as a Catholic martyrdom site. Licensed cultural heritage guides conduct tours (Korean only — bring a translation app), and the fortress is open year-round even outside festival season.

💡 Looking for the best deals on accommodation near Seosan? Booking.com and Agoda offer easy English-language booking with international card payment — search “Seosan” or “Cheonan” for options near the festival!

Planning your full trip around the Haemi Eupseong Festival? Use Trip.com or Klook to compare day-trip tours from Seoul to Seosan during the festival weekend. Some tour packages from Seoul include roundtrip transport — a convenient option for travelers who prefer not to navigate Korean bus terminals independently. Book early, as festival weekend packages sell out well in advance.

7. Haemi Eupseong: Full Historical Tour Guide

Key Historical Sites Inside the Fortress

Haemi Eupseong is one of South Korea’s best-preserved Joseon Dynasty walled towns, designated as Historic Site No. 116. The fortress perimeter wall stretches approximately 1.8 km and takes about 30–40 minutes to walk at a leisurely pace. Entering through the West Gate (진남문, Jinnam Gate) leads visitors first to the Dongheon (동헌) — the local government office — and Naea (내아) — the magistrate’s residence. The most historically significant site for many international visitors is the Catholic Martyrdom Site (자리개질 처형 터), where thousands of Korean Catholics were executed during the Joseon-era religious persecutions of the 19th century. This site is part of the Korean Martyrs Heritage, on UNESCO’s Tentative World Heritage List. The fortress is open year-round and is well worth a visit even outside of the festival season. Cultural heritage guide tours may be arranged through Seosan City (+82-41-681-3560).

Festival-Period Historical Experience Programs

During the 2026 festival, a range of hands-on historical programs will be offered alongside the main performances. These are expected to include the King Taejong Royal Military Procession (태종대왕 행렬) reenactment, traditional costume experiences, Joseon-era martial arts demonstrations, and children’s cultural activities. Some experience programs may be available on a first-come, first-served basis at the venue — arriving early gives you the best access. For the most up-to-date program schedule and availability, check the official festival page on VisitKorea English or call the 1330 Korea Tourism Helpline. English signage availability inside the fortress may be limited; the Kakao Map or Google Translate camera mode can help with Korean signage.
