Top 10 Fishing Spots in South Korea
South Korea does not make many global fishing itineraries, yet the country rewards those who look closely. Its southern coast opens onto the Korea Strait, where nutrient-rich currents push trophy-size red sea bream and flounder within reach of a half-day charter. Inland, a network of dammed river reservoirs holds largemouth and smallmouth bass so well conditioned that Korean anglers have built a serious competitive circuit around them. Between the volcanic shores of Jeju Island and the alpine streams of Gangwon Province, the peninsula offers more angling variety than many countries ten times its size.
Sea Bream and Flounder off Jeju Island
Jeju Island sits roughly 90 kilometres south of the mainland, swept by the Tsushima Current that carries warm, highly oxygenated water from the East China Sea. Red sea bream — called dom in Korean — gather around the island's basalt reef ledges from April through November. Charter boats out of Seogwipo and Jeju Port typically anchor over structure at 20–40 metres, using small squid strips or live shrimp on dropshot rigs. Fish averaging 1–2 kg are common; specimen anglers targeting fish over 3 kg focus on the deep western reefs near Sanbang-san between September and October. Olive flounder (gwang-eo), another prized species here, inhabit sandy pockets between the reefs to 60 metres depth and take jigs or whole sandeel rigs fished slowly along the bottom.
Han River Bass Tournaments
The Han River reservoir system stretching west from Seoul — encompassing Paldang Lake and Chungju Lake — has become South Korea's freshwater bass heartland. Largemouth bass were introduced in the 1970s and have thrived in the clear, relatively warm water. Chungju Lake, impounded by the Chungju Dam at 97.5 square kilometres, is the largest reservoir and hosts several professional bass tournaments each summer. Anglers work Texas-rigged soft plastics and swimbaits around submerged timber, particularly in the Dalcheon arm and the shallower northern coves. Bass in the 2–3 kg range are caught regularly; fish exceeding 4 kg appear each season.
Nakdong River Delta — Coastal Mixed Bag
Where the Nakdong River meets the sea near Busan, shallow tidal flats and reed-lined channels hold spotted sea bass, mullet, and occasional flathead during summer. The delta's network of irrigation channels also connects to small ponds holding carp to 6 kg. Light lure fishing with minnow plugs in the narrow channels after dark is a popular local technique, particularly from May onward when spotted sea bass are actively feeding in the tidal push. The nearby Geoje Island ferry terminal is a reliable spot for yellowtail amberjack (buri) as juveniles arrive with the warm current in late spring.
East Sea (Sea of Japan) — Squid and Rockfish
Korea's east coast, along the East Sea, is renowned for squid jigging from late summer through autumn. The port of Pohang and Donghae see large fleets of squid boats heading 10–30 km offshore once darkness falls, each boat rigged with powerful LED arrays to attract the squid to the surface. Anglers using light squid jigs (egi) in the 2.5–3.5 size range routinely fill buckets in a single night session from August through October. Rocky headlands between Gangneung and Samcheok also hold black rockfish (bolrak) year-round, hitting small soft plastics and metal jigs worked over kelp-covered boulders in 5–15 metres.
Soyanggang Reservoir — Rainbow Trout in the Mountains
Soyanggang Reservoir in Gangwon Province, created by one of Asia's largest earth-fill dams, provides cold, clear water ideal for rainbow trout. Local trout farms alongside the reservoir regularly release fish for recreational angling, and a wild population sustains itself in the feeder streams. The reservoir opens for licensed angling from April, with the best trout fishing occurring in April–May and again in October–November when water temperatures drop below 15°C. Artificial lures including small spoons and inline spinners work well on the main body; fly fishing with nymph patterns suits the upper inflows near Inje.
South Sea Islands — Slow-Pitch Jigging for Amberjack
The archipelago of islands scattered across the South Sea between the Korean mainland and Jeju — including Wando, Geomundo, and Chuja Island — offers some of the country's best slow-pitch jigging. Yellowtail amberjack, greater amberjack, and red snapper hold over the complex bottom structure here, where underwater plateaus drop suddenly to 80–150 metres. Slow-pitch jig weights of 150–300 grams fished with deliberate vertical strokes account for amberjack to 8 kg in peak season (May–June and October). Local charter boats operate from Wando and Goheung.
Gyeonggi Bay — Tidal Flat Surfcasting
The broad tidal flats of Gyeonggi Bay, west of Seoul along the Yellow Sea coast, transform at low tide into kilometres of exposed sand and mudflat. At high tide, flatfish, croaker, and yellow corvina push onto the flats to feed. Surfcasting from the sea walls near Incheon and Siheung with bloodworm or sandworm baits targets these species. Yellow corvina (bumeo) runs particularly strong from late spring through early summer and is among the most commercially valued fish in Korean cuisine, adding extra motivation for anglers to target the species. The tidal range here exceeds 8 metres, creating powerful currents that concentrate bait fish.
Upstream Imjin River — Wild Trout and Chub
The Imjin River, flowing from North Korea through the Demilitarized Zone and into the Han, remains one of the most pristine large rivers on the peninsula precisely because its upper reaches have been effectively off-limits to development and heavy fishing for decades. Below the DMZ, the river holds wild brown trout and native Korean chub in deep pools between exposed granite boulders. Fly fishing with dry flies in June and nymphing through autumn are the preferred methods. Access requires registration with local fishing clubs and respect for strict conservation zones, but the reward is genuinely wild river fishing in a landscape barely touched since the Korean War.
Jeju Offshore — Blue Marlin and Tuna
Beyond the inshore fishing, Jeju Island serves as South Korea's offshore sportfishing hub. Blue marlin exceeding 200 kg have been caught in the deep water south and southwest of the island, where the bottom drops past 500 metres within 30–40 km of the shore. Trolling large skirted lures and rigged ballyhoo targets marlin from June through September. Yellowfin tuna also appear in good numbers in July and August, often visible in surface schools feeding on sardines. A handful of billfishing charter operators work out of Seogwipo with fully equipped vessels, outriggers, and fighting chairs.
