FAQ
Can divers actually reach Dokdo for diving?
Diving directly at Dokdo is extremely restricted and requires special permits from Korean authorities, which are rarely granted for recreational purposes. However, the waters around Ulleungdo and the approach route toward Dokdo offer excellent diving that is more practically accessible. Ulleungdo itself has several dive operators running boat dives to the surrounding islets and volcanic formations. The outer dive sites toward the southeast experience similar oceanic conditions to Dokdo, with clean East Sea water, strong currents, and pelagic marine life. Most international divers focus on Ulleungdo's established sites.
What is the best season for diving around Ulleungdo?
The diving season around Ulleungdo runs from July through October, with August and September offering the best combination of water temperature, visibility, and marine life activity. Water temperatures during peak season reach 20 to 24 degrees Celsius on the surface, though thermoclines can drop temperatures significantly at depth. Visibility is generally best in late summer when plankton blooms subside and oceanic currents bring clearer water. Ferry services from the mainland run more frequently during summer months, and dive operators are fully staffed. Winter diving is theoretically possible but impractical due to cold temperatures, rough seas, and reduced ferry schedules.
How do I get to Ulleungdo?
Ulleungdo is reached by ferry from several ports on Korea's east coast, primarily Pohang, Donghae, and Mukho. The crossing takes two to three hours by fast ferry. There is no airport on Ulleungdo. Ferry schedules can be affected by weather, particularly during typhoon season, so flexibility in travel plans is advisable. On the island, accommodation ranges from guesthouses to small hotels, and rental scooters or taxis provide transportation. Dive operators are concentrated in Dodong and Jeodong ports on the island's southeast coast.
How do I get to Ulleungdo Island?
Ulleungdo is reached by ferry from the east coast ports of Pohang, Mukho, or Gangneung on the Korean mainland. The ferry journey takes approximately 2.5 to 3 hours depending on the departure port and weather conditions. Ferries are frequently cancelled during rough weather, particularly in winter and early spring, so flexible scheduling is essential. There is no airport on the island. Most visitors plan a minimum three-day stay to account for potential weather delays.
What is the best time of year to dive Ulleungdo?
The peak diving season runs from late July through mid-September, when water temperatures reach 20 to 24 degrees Celsius and visibility is at its clearest, often exceeding 30 metres. Marine life is most active during this window. The island is diveable from June through October, but outside the peak window, water temperatures can be cold and ferry cancellations more frequent. Winter diving is possible for cold-water enthusiasts but requires dry suits.
