The gateway to Castlex Jeju Golf Club is Jeju International Airport, a compact hub on the island's northern coast served by frequent flights from Seoul, Busan, and across East Asia. From the terminal, the southward journey to Seogwipo unfolds over roughly an hour, tracing the island's volcanic spine as the landscape shifts from coastal plains to the dramatic southern highlands where tangerine groves give way to black basalt walls and glimpses of the sea. Private arrivals can coordinate through select FBOs at Jeju, though the island's modest scale makes the drive from the main airport both swift and scenically rewarding. The approach to Castlex delivers you to Seogwipo's quieter southern shore, where the club occupies a privileged perch above some of Jeju's most striking coastal terrain.
