Hallasan National Park is on Jeju island to the south of the South Korean mainland.
Hallasan (한라산 / 漢拏山) is the highest mountain in South Korea, standing at 1,950 meters (6,400 ft). The park is in the center of Jeju Island and the peak can be seen from almost all places on Jeju itself. It is a UNESCO World Natural Heritage Site.
The park is based around mountain of Hallasan which is a dormant volcano that last erupted in 1007, and only has one dominating peak. The top of the mountain has a crater lake known as Baekrokdam.
There are no fees to enter the park.
- Witse Oreum has a manned rest house and a very basic shop that sells coffee and ramen.
Take the regular precautions whilst hiking: ask locals about course conditions and tell someone where you are going. In reality, hiking in South Korea tends to be something akin to ant-trail winding up a mound, but in Winter, when the buses terminate early, and it gets dark early you could run into trouble. Seek and follow local advice from the base huts and be sure to depart before the daily course closure time.
