Hallasan is a shield volcano that is the highest mountain in South Korea.

It was designated a UNESCO Biosphere Reserve in 2002,[1] and a World Heritage Site in 2007.

It rises 1,950 m above sea level, which means that it is the highest mountain in South Korea.

This mountain was formed in the fourth Cenozoic era by the eruption of a volcano.

In the summit, there is a crater lake called “Baekrokdam.”[6] Since the mountain has high altitude, there are a number of alpine plants and animals.
