The Yeosu World Island Exhibition opened on 5 September 2026 and runs for 61 days through to 4 November, making it the biggest event in South Korea’s South Jeolla Province calendar this year. Billed as the world’s first international exposition with islands as its central theme, the event is centred on Yeosu’s existing maritime infrastructure and draws together exhibits from coastal and island nations on sustainable ocean use, maritime tourism, and community development.
Scale of the Event
Organisers have planned for approximately 3 million visitors over the 61-day run. The main exhibition zone covers eight themed pavilions, including sections dedicated to blue economy innovation, advanced air mobility (drone taxis and electric air taxis are being demonstrated on a short coastal route during the expo period), and island culture showcases from participating countries.
The venue is the Expo Ocean Park area on the Yeosu waterfront, built on reclaimed land for the 2012 Yeosu World Expo and now being activated again for the 2026 edition. Entry is ticketed; single-day passes and multi-day packages are available through the official website and at KTX train stations.
Getting to Yeosu
Yeosu is accessible from Seoul by KTX in approximately 3.5 hours from Seoul Station. The route runs via Gwangju and Suncheon. Direct KTX trains to Yeosu Expo Station (the closest station to the exhibition grounds) depart Seoul multiple times daily; reservations should be made in advance as trains through the expo period are heavily booked on weekends.
Flying is an option from Seoul’s Gimpo Airport on domestic routes operated by Korean Air and Jeju Air, with the flight taking about 50 minutes. Yeosu Airport is 10 minutes from the expo grounds by taxi.
Yeosu as a Destination Beyond the Expo
Busan is a natural pairing for a southern coast itinerary — it’s about two hours from Yeosu by train or bus, and together the two cities cover the best of Korea’s southeastern coastline. Yeosu’s own appeal outside expo season includes the Odongdo Island causeway walk, the Hyangiram Hermitage built into cliffs above the sea, and the cable car crossing the harbour entrance. The Geomundo and Baekdo island groups are accessible by ferry from Yeosu and offer a less-visited version of the island scenery that gives the expo its theme.
For those coming from Seoul and wanting to combine the expo with more mainland sightseeing, a guided tour from Seoul covering the southern provinces is a more efficient option than piecing together individual trains.
Practical Notes
- Peak crowds: Weekends through October will be the busiest periods. The last three weekends of October are also peak domestic holiday season.
- Accommodation: Yeosu’s hotel stock is limited; many visitors are staying in Suncheon (30 minutes by local train) and commuting in.
- Tickets: Purchase in advance from the official expo website. Day-of ticket availability is not guaranteed on weekends.
- Languages: Signage is in Korean, English, and Chinese. English-speaking staff are present at all main pavilions.
The Yeosu World Island Exhibition is a genuine international event — unusual for the region outside of Korea’s larger cities — and its 2026 timing coincides with ideal autumn weather on the southern coast.
