The valley is officially recognized as an 'Ice Valley' where ice formation is inversely proportional to ambient temperature.
During peak summer heat, the rocks at the site can reach near-freezing temperatures due to localized geological vents.
The 62-meter ice wall created in winter is a sanctioned venue for international ice-climbing competitions.
The site is designated as a protected natural landmark within the Cheongsong UNESCO Global Geopark.
The phenomenon is attributed to the internal structure of the rock talus, which acts as a natural cooling system through convection currents.
Cheongsong Eoreumgol Valley is a unique natural phenomenon where ice forms during the hottest months of the year. Located at the base of In-geunsan mountain, the valley is known for its strange microclimate where temperatures drop as the summer heat intensifies. The site features a 62-meter high artificial waterfall that serves as an ice-climbing destination during the winter months. Cold air currents emerge from the rocky crevices of the valley floor, creating a stark temperature contrast with the surrounding forest. The area is part of the larger Cheongsong UNESCO Global Geopark network, recognized for its rare geological features. Visitors can observe the geological rock formations characteristic of the volcanic activity that shaped this region millions of years ago. The site is equipped with wooden walkways and observation decks to provide safe access to the cliffside ice formations.
The observation deck directly facing the 62-meter tall cliff face.
Bring a light jacket even during mid-summer as the air near the rock face is significantly colder than the surrounding valley.
Wear shoes with good traction, as the walkways near the cliffs can be slippery due to condensation and mist.
Combine this visit with a trip to the nearby Juwangsan National Park for a full day of geological exploration.
Do not attempt to touch or climb the ice walls unless you are a registered participant in a sanctioned ice-climbing event.
Do not climb on the protected rock formations; keep noise levels low to preserve the natural atmosphere.
