Cheongsong
One valley here holds ice through the height of summer, and science still argues why.
In July, while the country sweats, a boulder field in Cheongsong grows ice: blue-white formations in the height of summer, steam rising from the forest around them. The mechanism is still debated.
Cheongsong's Eoreumgol ice valley keeps summer ice by a mechanism still argued over, cold air breathing from subsurface rock being the leading theory, and it anchors a UNESCO Global Geopark whose story spreads across spherulitic rhyolite, deep gorges and the 1.1-kilometre Flower Stone Ecotrail. Dalgi's spring water runs at a constant six degrees to deepen the mystery, and the county's famous apples, sweetened by extreme day-night swings, are the edible expression of the same strange geology.
Solo
Follow the flower-stone trail closely enough to read the rock textures before driving to a contrasting gorge.
Friends
Friends can divide navigation and interpretation across widely separated geosites in this large rural geopark.
Family
A short named ecotrail gives children a finite geology hunt before the longer road circuit.
Couple
Couples who enjoy landscapes with a puzzle can compare rhyolite patterns and the ice-valley phenomenon.
- Eoreumgol grows ice through the height of summer, mechanism still debated.
- The UNESCO geopark spreads across rhyolite, gorges and springs.
- Dalgi's spring water runs at a constant six degrees.
- Cheongsong apples sweeten on the same extreme day-night swings.
Cheongsong's yaksu dak-baeksuk is a whole-chicken soup cooked with local mineral water and served with mountain vegetables.
In early November, the county apple festival is the direct route to fresh Cheongsong apples and producer stalls.
