Jeju Travel Guide: Volcanic Island, Olle Trails & Black Pork BBQ

History & Cultural Influence

Jeju was an independent kingdom called Tamna until absorbed by mainland Korea in the 13th century. Its volcanic origin — Hallasan erupted about 25,000 years ago — produced the lava tubes, tuff cones and columnar cliffs that won UNESCO Natural World Heritage status in 2007. Jeju is also famed for its matrilineal haenyeo diving culture, where women dive without breathing apparatus to harvest abalone, sea urchin and conch — a UNESCO Intangible Cultural Heritage.

When is the best time to visit Jeju?

Mid-April for canola yellow fields and cherry blossoms, or late October for clear skies and Hallasan’s pampas-grass-covered oreum hills. Avoid the August typhoon window.
