Binggye Valley | 観光地情報 | K-Travel Mate

Binggye Valley is a valley attraction with beautiful natural scenery, designated as a county park. It consists of basalt and rhyolitic tuff formed by Mesozoic Cretaceous volcanic activity. The stream (Ssanggyecheon) flows from northeast to southwest, generally matching the direction of the fault passing through here. The main attractions are the 'ice hole' where ice forms and the 'wind hole' where cold air blows out, registered as the natural monument 'Uiseong Binggye-ri Ice Cave.' Especially, the ice hole has an average temperature of 0.3℃, more than 10℃ lower than the outside temperature, with the highest temperature throughout the year below 5℃, and it has the longest freezing period in Korea (early March to early October). This low-temperature phenomenon occurs because the columnar joints developed on the fluvial cliff create a talus slope formed by weathering and erosion. It is explained by heat exchange through air circulation, and the airflow direction formed in the talus changes with seasons because the temperature of the air stored in the talus and the outside temperature vary. In late autumn to winter, cold outside air enters the talus, continuously settling and getting trapped at the bottom. In spring to summer, cold air inside the talus exits through the bottom, blowing out more strongly while warm outside air enters the talus. Northern plant species like Jommiyokgosari and Handeulgosari appear near this area. (Source: Uiseong Geopark)
