About this site
Lobster Crack lies off the coast of Jeju Island, South Korea, near the southern tip of the peninsula at the point where the East China Sea meets the Korea Strait. Jeju's coastline is volcanic in origin, formed by basalt flows, and diving around the island typically takes place along rocky reef and lava formations. This site reaches a maximum depth of around 30 metres over reef terrain and is rated an advanced dive.
