About Chiaksan
Chiaksan, between Wonju and Hoengseong, is the guardian mountain of Wonju and a famous peak of the Yeongseo region. It became a provincial park in 1973 and a national park in 1984.
Around its main peak, Birobong, stand Namdaebong, Hyangnobong, Cheonjibong and Maehwasan, many over 1,000 m. The ridge and valley running north from Birobong toward Guryongsa are famously steep.
Royal pine boundary stones, which once protected timber for the court, survive in its forests.
