Natural Monument—Ryonju Pools
Ryonju Pools are located in Okryu Valley of Kuryongyon District of Outer Kumgang in Onjong-ri, Kosong County, Kangwon Province.
There is a steep cliff north of the pools and Kuryong Pond 400 metres southwest of them.
Ryonju Pools are so named as the two pools look like stringed two beads. They came into being by the weathering of glacier and water.
The upper pool is 10 metres long , 5 to 6 metres wide and 6 metres deep, and the lower one, 20 metres long, 8 to 9 metres wide and 9 metres deep.
There is a 3-4-m high waterfall between the two pools.
Ryonju Pools go well with surrounding mountains, presenting a beautiful landscape.
