When to go to Jeju?

Jeju is a volcano with an island around it. Hallasan, 1,947 m, holds the middle, with trails up through dwarf bamboo to a crater lake, while the tuff cone of Seongsan Ilchulbong rises out of the sea on the east coast and is climbed for sunrise. Manjanggul runs underground as a lava tube, and the white sand of Hyeopjae closes the day on the west.
