Chiaksan National Park

Character

Chiaksan is arranged less like a single mountain outing than a set of separate approaches into the same steep ridge system. Birobong, the 1,288-metre summit, sits toward the north; Namdaebong anchors the southern end, and valleys cut into the mountain from several directions

The Guryong side carries the broadest mix of experiences. A forest approach reaches Guryongsa, then continues through Guryong Valley toward Seryeom Falls; the longer route keeps climbing to Birobong. Near the temple, the Hwangjanggeumpyo stone records a different use of the forest: in the Joseon period, unauthorized cutting of selected royal timber was prohibited here

Other gateways change the mountain quickly. Hwanggol provides another route toward Birobong from the west, while Geumdae and Seongnam open the southern ridge around Namdaebong. KNPS lists these as distinct trail systems, not branches of one visitor circuit

The experience

At Guryong, the first part of the day can remain low in the valley. The route passes the temple precinct and follows water and forest toward Seryeom Falls before the terrain becomes much more demanding on the climb toward Birobong

The summit routes are physically different from that lower valley sequence. Chiaksan is known for steep grades and rocky sections, and KNPS classifies several of its longer routes in the advanced ranges. The park also has a 14-kilometre ridge line linking the Birobong and Namdaebong areas, giving experienced hikers a much larger mountain than the popular Guryong approach alone suggests

The southern side has its own cultural anchor at Sangwonsa below Namdaebong. In Wonju’s version of the pheasant-repayment legend, a traveler saves a pheasant from a snake; later, when a snake threatens him unless a temple bell rings, pheasants strike the bell with their heads and die. The tale says the mountain’s older name, Jeokaksan, was replaced with Chiaksan using the character for pheasant

History

Chiaksan’s Buddhist history is older than the national park. Guryongsa is traditionally said to have been founded by Uisang in 668, although modern scholarship notes that firm early records are lacking and that the surviving temple buildings reflect later Joseon-period rebuilding. The present complex therefore carries both an ancient foundation tradition and a much later architectural history

The Hwangjanggeumpyo near Guryongsa gives the surrounding forest a more material Joseon-era history. The stone marker prohibited unauthorized logging in pine forest reserved for royal use

Chiaksan was designated South Korea’s 16th national park in 1984. Today the protected area reaches across the Wonju and Hoengseong side of a mountain whose steep valleys, temples, fortification remains and ridge trails had already accumulated very different histories

Before you go

Trail choice matters more here than a single park entrance. The Guryong approach works for a short temple-and-valley visit as well as a summit day, while Hwanggol and the southern trailheads lead into different sections of the ridge. Entry-time controls and weather closures can affect mountain trails even when lower approach areas remain accessible
