We departed Busan by air for a 50 minute flight across the Korean Sea to the island of Jeju. Jeju is a volcanic island with one major mountain and 360 volcanoes. The last eruption was 5,000 year ago. It is a tropical island with everything you would expect, included many tourist resorts.
The coastline of the island is a postcard at every angle.
Long day hikes on coastal trails. Lot of steps.
