Jeju

Jeju is a coastal city on the volcanic island of Jeju in South Korea, known as a gateway to regional diving in the Korea Strait. The island hosts a handful of dive centers offering local boat dives to accessible reefs, wrecks, and underwater features around Jeju’s volcanic coastline. Dive conditions are typically warm for the region, with moderate visibility and a mix of rock, sandy bottoms, and occasional macro life. While Jeju isn’t a mass-market dive hub, it provides practical access for short trips and training, especially for visitors staying on the island. Expect practical options for beginners and experienced divers alike, with center-based instruction and equipment rental available near the coast. The surrounding seas connect divers to nearby bays and coastal sites, with freshwater opportunities limited to training facilities on the island.
