May is one of the best months to visit Seoul. The weather is usually mild, outdoor events become easier to enjoy, and many of the city’s most interesting cultural festivals take place across central Seoul, the Hangang River, DDP, Jongno, Seongsu, and Seoul Forest.
If you are visiting Seoul in May 2026, this guide introduces some of the best festivals and events foreign tourists can enjoy. The first three events are especially recommended because they are visually impressive, easy to access, and strongly connected to Korean culture or Seoul’s modern travel scene.
Before visiting any event, always check the official website or event page for the latest schedule, venue updates, reservation requirements, and weather-related changes.
1. Lotus Lantern Festival 2026: Seoul’s Most Beautiful Traditional Night Festival
Event Dates: May 16–17, 2026
Main Parade: May 16, 2026, 7:00 PM–9:30 PM
Main Area: Jongno Street, from Heunginjimun Gate toward Jogyesa Temple
Best For: Culture lovers, photographers, first-time visitors, night festival seekers
Admission: Free to watch
Official Website: Lotus Lantern Festival official website
Inquiry: +82-2-2011-1740
The Lotus Lantern Festival, known in Korean as Yeondeunghoe, is one of the most beautiful traditional festivals you can experience in Seoul. In 2026, the main lantern parade is scheduled for May 16 from 7:00 PM to 9:30 PM, running along Jongno Street from Heunginjimun Gate toward Jogyesa Temple. The wider festival period is listed as May 16–17, 2026.
This festival is especially meaningful because Yeondeunghoe has a long history of around 1,200 years and is recognized as a UNESCO Intangible Cultural Heritage of Humanity. It began as a Buddhist tradition but has become one of Seoul’s major cultural festivals, attracting both local residents and international visitors.
The highlight is the night parade. Thousands of lanterns move through central Seoul, creating a glowing street scene filled with lotus flowers, dragons, Buddhist symbols, traditional costumes, music, and large illuminated lantern floats. For photographers and first-time visitors, this is one of the most memorable night events in Seoul.
One reason this event is so good for foreign tourists is that it combines several things travelers often want from Seoul: Korean tradition, night photography, temple culture, street atmosphere, and easy subway access. You can visit Insadong, Jogyesa Temple, Cheonggyecheon Stream, Gwanghwamun, or Bukchon during the day, then move toward Jongno in the evening for the parade.
What to See at the Lotus Lantern Festival
The main event is the lantern parade, but the festival also includes traditional lantern exhibitions, cultural performances, Buddhist cultural programs, and post-parade celebrations. Visit Korea lists the festival programs as including traditional lantern exhibitions, Eoulim Madang, Daedong Hanmadang, traditional cultural events, and cultural performances.
For visitors, the best experience is usually to arrive early, find a place along the parade route, and stay until the lanterns begin moving through Jongno after sunset.
Travel Tips for Foreign Tourists
Because Jongno becomes very crowded during the parade, it is better to use the subway rather than a taxi. Bring a transport card, check your route before leaving your hotel, and arrive earlier than you normally would. If you plan to take photos, choose a spot before the parade begins instead of trying to move through the crowd later.
For the latest parade route, program details, and visitor updates, check the official Lotus Lantern Festival website before you go.
2. Seoul Friendship Festival 2026: A Global Culture Festival at DDP
Event Dates: May 9–10, 2026
Time: 12:00 PM–9:00 PM
Venue: Dongdaemun Design Plaza, DDP
Best For: Food lovers, families, culture seekers, first-time visitors
Admission: Free
Official Info: Visit Seoul / Seoul Culture Portal / Seoul Friendship Festival official channels
The Seoul Friendship Festival is one of the easiest May events to recommend to foreign tourists. In 2026, the festival is scheduled for May 9–10 at Dongdaemun Design Plaza, also known as DDP. Official event information lists the festival time as 12:00 PM to 9:00 PM.
This event is attractive because it is international, central, and easy to understand. Instead of being only a local Korean festival, Seoul Friendship Festival brings together global culture, international performances, food, and cultural booths. For visitors who are new to Seoul, it offers a comfortable way to experience the city’s global side while staying in one of its most famous modern landmarks.
DDP itself is already a popular tourist stop. It is known for its futuristic architecture, night views, fashion-related atmosphere, exhibitions, shopping areas, and convenient subway access. Because of this, Seoul Friendship Festival is easy to combine with Dongdaemun shopping, night photography, nearby markets, or a casual evening walk.
What to Expect at Seoul Friendship Festival
Visitors can expect international cultural performances, food booths, global city/country booths, and cultural experience programs. Previous and current official festival information describes the event as a place where different cultures come together in Seoul, making it especially suitable for foreign visitors, families, and travelers who want an easy festival experience without needing Korean-language knowledge.
For tourists, the strongest points are convenience and variety. You can stop by during the afternoon, try different foods, watch performances, walk around DDP, and stay into the evening when the area becomes more photogenic.
Why It Is Good for Foreign Tourists
This festival works well for foreign tourists because it is not difficult to access or understand. The venue is well known, the event is free, and the international theme makes it friendly for visitors from many countries.
It is also a good choice for travelers who do not want a full-day festival plan. You can visit for a few hours, then continue to another area such as Myeongdong, Gwangjang Market, or Cheonggyecheon.
Visitor Tip
Because the event is held at DDP, the subway is the easiest way to get there. Check the official event page before visiting for updated booth details, stage schedules, and any crowd-control notices.
3. Seoul International Garden Show 2026: Seoul Forest, Seongsu, and a Long-Running Outdoor Festival

Main Content: Garden displays, pop-up gardens, cultural programs, market areas, outdoor walking routes
Official Info: Seoul official English website / Visit Korea
Inquiry: +82-2-550-2532
The Seoul International Garden Show 2026 is one of the most useful events for travelers because it runs for a long period. The event period is listed as May 1 to October 27, 2026, which means it is not only a May event but also a spring, summer, and early autumn attraction.
For 2026, Seoul has announced that the garden show will expand from Seoul Forest into the broader Seongsu-dong area, connecting one of Seoul’s most popular parks with one of the city’s trendiest neighborhoods. Seoul’s official English site describes the 2026 garden show as expanding from Seoul Forest to the wider Seongsu-dong area beginning May 1.
This makes the event especially attractive for foreign tourists. Seoul Forest is already a good place for a relaxed walk, while Seongsu is popular for cafés, fashion pop-ups, design shops, lifestyle stores, K-beauty spaces, and photo spots. The garden show gives visitors another reason to spend half a day in this area.
What to See at the Seoul International Garden Show
The event includes themed gardens, garden displays, garden markets, cultural programs, docent programs, flea markets, and food trucks. Visit Korea lists the event as featuring garden displays, a garden market, cultural programs, docent programs, a flea market, and food trucks.
For foreign travelers, the best way to enjoy this event is not to rush. Start at Seoul Forest, walk through the garden areas, take photos, and then continue into Seongsu for cafés, shopping, or beauty-related experiences.
If you are interested in the beauty and lifestyle side of Seongsu, you can also read our guide to Best Free K-Beauty Experiences in Seoul for Foreign Tourists before planning your Seoul Forest and Seongsu itinerary.
Why It Works Well for Foreign Tourists
This event is less crowded and less intense than a night parade or major performance festival. It is better for visitors who want a calm daytime activity, a scenic walking route, or a relaxed Seoul itinerary.
It is also strong for repeat visitors. If someone has already visited Gyeongbokgung, Myeongdong, Hongdae, and Bukchon, Seoul Forest and Seongsu offer a more local and modern side of Seoul.
Visitor Tip
Check the official Seoul International Garden Show information before visiting because garden locations and pop-up programs may change during the long event period. Comfortable shoes are recommended because the event is best enjoyed as a walking route.

This is a very Seoul-specific experience. Jamsugyo Bridge becomes car-free, allowing visitors to walk across the bridge, enjoy performances, explore food trucks or market areas, and take photos of the Hangang River.
It is especially good for travelers who want a local weekend experience rather than a typical tourist attraction. It also pairs well with Banpo Hangang Park, sunset views, and evening walks near the river.

Travel Tips for Enjoying Seoul Festivals in May
Use the Subway Whenever Possible
Many May festivals take place in busy areas such as Jongno, DDP, Yeouido, Banpo, and Seongsu. During major events, roads can be crowded or restricted, especially near parade routes and Hangang festival zones. The subway is usually the easiest and most predictable way to move around Seoul.
If this is your first time using public transport in Korea, read our full guide to Transportation in Korea: Complete Guide for Tourists before planning your festival route.
Prepare Mobile Data Before You Go
Festival visitors often need to use maps, translation apps, subway apps, taxi apps, and official event pages while moving around Seoul. Having mobile data ready can make your trip much smoother, especially if you are visiting crowded outdoor events.
To check festival maps, subway routes, translation apps, and official event updates while moving around Seoul, it helps to have mobile data ready before you arrive.
Check South Korea eSIM options with Saily before your trip.
Arrive Early for Night Events
For major night events like the Lotus Lantern Parade, arriving early is important. Good viewing spots can fill up quickly, and it may be difficult to move around once the parade begins.
Check Official Pages Before Visiting
Outdoor festivals may change depending on rain, crowd control, or city operations. Always check the official website, event page, or Instagram before heading out.
Combine Events with Nearby Attractions
Many of these events are located near popular tourist areas. You can combine:
- Lotus Lantern Festival with Insadong, Jogyesa Temple, Cheonggyecheon, or Gwanghwamun
- Seoul Friendship Festival with DDP, Dongdaemun shopping, or Cheonggyecheon
- Seoul International Garden Show with Seoul Forest and Seongsu cafés
- Hangang events with Banpo, Yeouido, or riverside picnic plans
If you are planning to visit Seoul during major May festivals, hotel location can make a big difference. Areas near Jongno, DDP, Yeouido, Hongdae, Myeongdong, or Seongsu may help reduce travel time between event

Final Thoughts
May 2026 is a great time to visit Seoul if you enjoy festivals, outdoor walks, cultural events, and local city experiences. The Lotus Lantern Festival is the most visually powerful traditional event, the Seoul Friendship Festival is the easiest free global culture event to enjoy at DDP, and the Seoul International Garden Show is perfect for travelers who want a slower outdoor experience around Seoul Forest and Seongsu.
If your travel dates match one of these events, it is worth adding at least one festival to your Seoul itinerary. Just remember to check the official event information before visiting, especially for outdoor programs, parade routes, reservation-based activities, and weather-related changes.
