Osaek Mineral Spring (오색약수터)

Osaek Mineral Spring is situated 20 kilometers west of Yangyang and 7.5 kilometers southeast from Hangyeryeong Pass. The water, which springs from three base rocks by a brook, is carbonated and rich in iron. Up to 1,500 liters of iron-rich water spring out on a daily basis. Osaek became well known due to the splendid landscape leading up to the mineral spring and its location on the way to the summit of Seoraksan Mountain.
