Korea's highest peak (1,950m). Dormant volcano with a crater lake at the summit.

UNESCO crater erupted from underwater 100,000 years ago. Sunrise from the rim is on every Korean's bucket list.

Tiny 6km² island accessible by ferry. Rent an electric scooter, eat peanut ice cream, swim in Caribbean-blue water.

The most absurdly turquoise water in Korea. Shallow, warm, reef-sheltered.

One of the world's longest lava tubes — 1km walk through an underground alien world.
