Quick answer: The 2026 Yeosu World Islands Expo runs September 5 to November 4, 2026 (61 days) in Yeosu on Korea’s south coast, under the theme “Connecting Islands, the Sea, and the Future.” It’s the world’s first international exposition built entirely around islands — using Yeosu’s roughly 365 surrounding islands and coastline as exhibition space rather than a single fairground. The main venue sits in Dolsan’s Jinmo District, with satellite programming on nearby Gaedo and Geomundo islands and the old 2012 Yeosu Expo grounds. Around 30 countries are taking part, and eight themed pavilions anchor the Dolsan site — Theme Island, Marine Ecology Island, Future Island, Culture Island, Treasure Island, International Exchange Island, and a restaurant and market zone. Advance tickets are on sale now at a discount that steps down as the opening approaches.

What Is the Yeosu World Islands Expo?
Yeosu already hosted a Registered World Expo once, in 2012, under an ocean-and-coast theme. The 2026 edition is a different kind of event: rather than a single fairground with pavilions from participating nations, organizers built it as a multi-site festival that treats the region’s islands — Yeosu counts roughly 365 of them — as the exhibition itself. The theme, “Connecting Islands, the Sea, and the Future,” frames the expo as a showcase for how small island communities can pilot sustainable development, marine conservation, and climate adaptation, with international partner countries contributing exhibits and programming across the venues rather than in a single national-pavilion row.
The expo has drawn some domestic scrutiny over construction timelines in the months before opening, with local coverage flagging that parts of the main site were still under construction earlier this year. As of the run-up to the September opening, organizers report the eight main pavilions and site sculptures largely complete, with finishing work continuing on landscaping and visitor infrastructure — worth keeping in mind if you’re visiting close to opening week rather than later in the two-month run.
Where Is It Held, and What Can You See?
The primary venue is the Jinmo District on Dolsan Island, connected to central Yeosu by the Dolsan Bridge, with the eight themed pavilions arranged along the waterfront: a Theme pavilion introducing the expo’s island concept, a Marine Ecology pavilion, a Future pavilion focused on island technology and sustainability, a Culture pavilion, a Treasure pavilion, an International Exchange pavilion for participating countries, and a combined restaurant and market zone for food and local products. Beyond Dolsan, programming extends to the smaller islands of Gaedo and Geomundo and reuses parts of the original 2012 Expo grounds on the mainland side of the harbor, so a single-day visit realistically covers only a portion of the full site — it’s built more like a regional festival circuit than a compact fairground you can see in an afternoon.
How Much Are Tickets, and When Should You Buy?
Advance tickets are sold in stepped discount tiers that shrink as the opening date nears — the earliest presale window offered the deepest discount (up to 40% off), and by summer 2026 the expo has moved into a later tier discounted closer to 20% off gate price, running through early September before the show opens. Tickets are sold online through Interpark’s Nol Ticket platform and in person at the expo organizing committee’s office in Yeosu; full pricing by ticket type (adult, youth, multi-day passes) is posted on the official Yeosu World Islands Expo site, which is the source to check closer to your visit for the current tier and any single-day promotions.
How Do You Get to Yeosu From Seoul?
Yeosu sits at the southern tip of Jeollanam-do, roughly 400 km from Seoul — too far for a same-day round trip, so most visitors from Seoul plan it as an overnight or multi-day trip rather than a day tour. The fastest option is the KTX high-speed train from Yongsan or Seoul Station direct to Yeosu Expo Station, a journey of around three hours; note that Korea’s two high-speed rail operators are in the middle of merging their booking apps into a single system this year, so it’s worth checking which app currently handles your route before you book. From Yeosu Expo Station, the Dolsan venue and downtown Yeosu are a short taxi or local bus ride away. If you’d rather fly part of the way, domestic flights connect Gimpo or other regional airports to Yeosu Airport, though for most inbound travelers arriving through Incheon, it’s simplest to route through Seoul first and continue south by rail.
If you’re still booking your flight into Korea, it’s worth comparing current fares to Seoul✈️ before you lock in your Expo dates, and pairing the trip with onward KTX travel south once you land.
Where Should You Stay?
Yeosu’s own hotel supply is modest compared to Seoul or Busan, so it’s worth booking well before the expo opens — rooms near the harbor and Dolsan Bridge fill up fastest for a two-month run expected to draw heavy domestic and regional traffic. Our where to stay in Yeosu guide compares Dolsan’s resort strip against the walkable downtown near Expo Station and rounds up verified hotels in each. If you’re combining the trip with more of Korea’s south coast, our Busan travel guide covers the region’s other major coastal city, reachable from Yeosu by rail, and our 7-day Korea itinerary shows how to fit Seoul and a southern add-on like Yeosu into a single trip.
