Top 10 Korean Islands to Visit

Ulleungdo is a remote volcanic island rising 130 kilometers from the East Sea, inhabited by just 10,000 year-round residents who harvest wild greens, squid, and pumpkin makgeolli unavailable anywhere else in Korea. Its circumnavigation ferry route reveals sheer basalt sea cliffs and dramatic sea caves, while the island's pristine hiking trails see 80% fewer tourists than Jeju Island, offering solitude and raw geological beauty. The island's isolation preserves a distinct culture and ecosystem: over 200 species of plants are endemic to Ulleungdo, and the squid fishery here accounts for 15% of Korea's yearly catch. This combination of exclusivity and natural spectacle makes it a compelling alternative to crowded destinations.

Geojedo, Korea's second-largest island by area, is connected by bridge to the mainland near Tongyeong and serves as a gateway to the Hallyeo Maritime National Park. It is renowned for the historic Okpo naval base, the sweeping Windy Hill panorama, and as the filming location of the drama Descendants of the Sun. The southern tip's Haegeumgang sea cliffs—towering rock formations best seen from a sunrise cruise—draw 30% more visitors annually than Namhaedo's German Village, thanks to their dramatic beauty. With over 700 kilometers of coastline and a network of mountain trails, Geojedo offers diverse outdoor experiences; the island's annual tourism receipts exceed 800 billion won, underscoring its significance.

Namhaedo, connected by the Namhae Bridge to the South Gyeongsang coast, is home to the unique German Village—a community of Korean returnees from West Germany built in European architectural style—and terraced rice paddies carved into steep seaside hillsides. The Coastal Road 3 circuit by bicycle is one of the finest cycling routes in southern Korea, offering 60% fewer elevation changes than Geojedo's mountain trails, making it accessible to casual riders. The island also features the Boriam Hermitage perched on a cliff and the Gacheon Daero seaside road, which draws 500,000 visitors yearly. Its blend of cultural history and gentle terrain sets it apart from more rugged island alternatives.

Wando produces the finest seaweed in Korea, with cold currents yielding kelp that contains 40% more alginate than the national average. Abalone and sea mustard from these waters are premium ingredients trusted by top Korean chefs, outperforming the seaweed from #6 Muuido in blind taste tests conducted by the National Fisheries Institute. Over 80% of visitors rate Wando as their top departure point for island hopping across the southern archipelago, a logistical advantage that #7 Imjado cannot match due to its limited ferry connections.

Muuido offers a complete escape from Seoul just 20 minutes from Incheon Airport, a contrast that is 40% more immediate than the next closest island on this list, #5 Wando. Its mudflat tidal walks and Silmi Beach’s rock formations draw repeat visitors for local crab and clam restaurants, where prices are 30% lower than mainland seafood markets—a value gap that #8 Bijindo cannot replicate due to its smaller fishing fleet. The island’s proximity to the capital makes it the most accessible weekend getaway, with 75% of guests arriving for day trips.

Imjado’s Purple Island project won the United Nations Public Service Award for community arts revitalisation, an accolade that no other island on this list, including #5 Wando, has achieved. Every June, the lavender fields and purple-painted bridges create the most spectacular single-season spectacle on any Korean island, attracting 50,000 more visitors than the average island festival—a crowd that exceeds #6 Muuido’s annual mudflat festival by 20,000. The initiative transformed the local economy, increasing tourism revenue by 300% since 2019.

Bijindo surpasses even #5 Wando in biodiversity conservation awards, protecting rare plant species found only in its micro-ecosystem. The island’s rope-pulling festival during Chuseok preserves traditions unchanged for over 50 years, with a retention rate of 90% of local customs—a cultural continuity that #7 Imjado lacks despite its modern makeover. A single daily ferry from Tongyeong limits visitors to under 200 per day, ensuring an atmosphere that 95% of guests describe as unchangingly authentic.

The most remote inhabited island in the Dadohae Marine National Park, accessible by ferry from Mokpo, is home to a forest of ancient camellia trees that canopy the mountain trails in flowering red in February. This secluded paradise, even less visited than Jeju Island, supports a fishing village of just 200 residents operating the most sustainable abalone aquaculture operation in Korea, producing over 50% more premium abalone per square meter than the national average.

A pair of volcanic rocks 87 kilometres east of Ulleungdo that are the easternmost territory of the Republic of Korea, Dokdo's designation as a natural protected area for seabirds has made it the most politically charged and emotionally significant island in Korea. Visitor permits are limited and the coast guard presence is constant, making arrival one of the most memorable experiences in Korean travel.
