Key Information

Jeju Island

Type Volcanic Island
Area 705 square miles
Highest Point 6,400 ft

Learning Point

  • Jeju Island is a volcanic island, which means it was formed by volcanoes! Millions of years ago, hot melted rock called magma erupted from deep inside the Earth and cooled to form the island’s land. You can still see signs of this volcanic history today, like the tall mountain called Mt. Halla or Hallasan, which is actually an extinct volcano. There are also many smaller volcanic cones and lava tubes scattered across the island, reminding us of the powerful forces that shaped this beautiful place.
