Blue Canyon, a leisure pool-type theme water park, is a high-quality water play space created by the clean air of Gangwon-do and the clean water of a deep valley. There are various lounges and play facilities, and it is a place where you can enjoy the thrill created by Korea's first 140m uphill slide and Korea's longest 201m and maximum 5m wide extreme river. The first-class natural mineral water, which gushes out from 700 meters underground, contains as many natural ingredients as hot spring water, so everyone from children with sensitive skin to adults can enjoy swimming in the water in a healthy way, making it a place loved by family tourists.
