Jeju is the capital of Jejudo island, which might just be the most popular holiday destination you’ve never heard of. The small island features white sandy beaches, turquoise waters, dramatic volcanic landscapes, and spectacular underground caves, and is often viewed as the Korean equivalent to Hawaii. Jejudo also has plenty of casinos, which help lure tourists from China, and, thanks to the island’s self-governing status, no visa is required for a visit.
