Onyang Hot Springs is the oldest hot springs complex in Korea, a place where the kings of Joseon (1392-1897) recuperated and bathed, thanks to its proximity to Seoul. In the 1970s and 1980s, it was a popular honeymoon destination. The water here has a temperature of about 44-60℃ and contains substances that are beneficial for the human body. The area boasts a large number of hotels and water parks.
