Best Time To Visit Jeju
A month-by-month guide to weather, crowds, and travel conditions in Jeju, South Korea.
About Jeju
Jeju is Korea's holiday island: Hallasan's dormant volcano, Manjanggul's lava tubes, the black-sand cliffs of Yongmeori, tangerine orchards, and the haenyeo free-diving women who harvest the sea without tanks. Seoulites fly down for weekends; the coastal road trip is the point.
