Springwater Area in Upper Gwangryeongcheon on Hallasan Mountain Designated as Natural Monument

Large-Scale Groundwater Discharge at 1,000 Meters Above Sea Level
Significant Underground Water Flows Observed in Highland Area
Supplying 10,000 Tons Daily, Serving as a Key Water Source for Jeju's Mid-Mountain Regions

Volcanic rock layer and hot spring water root zone

The springwater area located in the upper reaches of the Gwangryeongcheon stream on Hallasan Mountain is now designated and managed as a Natural Monument.

The National Heritage Administration announced on March 16 that the “Eorimok Valley Springwater Area of Hallasan Mountain,” situated at an elevation of 1,020 to 1,350 meters above sea level, has been designated as a nationally designated natural heritage site and Natural Monument.

In Jeju Island, most springwater sources are typically found along the coastline. In contrast, Eorimok Valley is notable for its rarity, as large-scale underground water flows can be observed in this highland area. In the valley, which is about 200 meters deep, a significant amount of water emerges along the impermeable layers between lava beds. An official from the National Heritage Administration explained, “This area provides key clues for understanding the hydrologic circulation and groundwater outflow structure of volcanic Jeju Island.”

This area is also abundant in water resources. Since the 1970s, an average of 10,000 to 12,000 tons per day has flowed out, serving as a water source for the mid-mountain regions of Jeju. Having been designated early on as a natural protection zone and water source protection area, its natural form has been well preserved. An official from the National Heritage Administration stated, “The combination of volcanic rock layers, valley cliffs, and moss waterfalls creates a harmonious landscape, adding to its ecological value as a habitat worthy of preservation.”
