A man, called Paek Un Hak, looked round Mt Kumgang and admired the superb view of the mountain, but felt sorry for the absence in such a renowned mountain of mineral water that can cure people of disease.
With a determination to discover one, he began to climb the valleys. His survey lasted for months. He was so exhausted that he could wander about no longer.
One day, after climbing up and down the mountains from the morning, he felt worn out and began to go down the Manphok Valley. Then he saw a blue crane with a broken wing flying past the woods. Wondering where the wounded crane would go, he followed it.
To his surprise, it landed at a spring at the foot of a towering peak, drinking the water and applying it to the affected wing.
It drank the water several times, tried flaps and flew up straight to the high mountaintop.
Un Hak rushed promptly to the spring.
It was a small spring formed by the water gushing out of the bottom of a high cliff.
Thirsty and worn out, he gulped down a few mouthfuls of water; it alleviated the pains of the limbs and invigorated him.
Consequently, the spring came to be known as the Kumgang Mineral Spring.
The mountain featuring it was named Paegundae after the name of its discoverer.
There is an old saying, “Don’t say you’ve been to Inner Kumgang without climbing Paegundae.” This saying originated not only from the scenery of the mountain but also from the popularity of the mineral water below it.
An old book reads, “This water is mild and clean, and tastes good all the time. When it is swelteringly hot, the water is as cold as ice or snow and effective for treating a hundred diseases.”
