Chiaksan National Park is located in the province of Gangwon-do, South Korea. It was designated as the 16th national park in 1984. The park is named after the 1,288-metre (4,226 ft) mountain Chiaksan, which in turn had its name changed from Jeokakasan to Chiaksan, meaning "Phesant Peak Mountain", based on a myth about a man who saved a phesant from being eaten by a snake. The park is home to a total of 821 plant species and 2,364 animal species. Among the animals 34 are endangered, including Flying squirrel and Hodgson's Bat.
