Chiaksan National Park is defined by its dramatic ridgeline, featuring the 1,288-meter Birobong Peak as its highest point. The park is characterized by steep, rugged granite rock formations and dense deciduous and coniferous forests. It encompasses the Guryongsa Temple, a significant historical site founded during the Silla Dynasty. The terrain is known for challenging hiking trails, including the notably steep 'Sadari Byeongchang' path. Its name, Chiaksan, translates to 'Pheasant Mountain,' derived from a traditional Korean folk legend about a pheasant and a snake. The park serves as a protected sanctuary for diverse flora and fauna, including endangered species like the flying squirrel and the Siberian musk deer. High-elevation areas offer panoramic views over the Wonju basin. The park provides varied trail difficulties, ranging from temple-access paths to multi-peak ridge traverses.

Bring trekking poles, as the trails are consistently steep and involve many stone steps.
Carry a physical map or ensure your GPS is charged, as cellular reception can be intermittent in deep valleys.
Pack a portable power bank, as cold temperatures or navigation apps can drain batteries rapidly.
Attempting the summit trail late in the day, as many paths are restricted after early afternoon for safety reasons; underestimate the difficulty of the steep stone staircases.
Trail access may be restricted during periods of high wildfire risk or extreme weather events; typically closed during peak dry seasons in spring and autumn.
Strictly follow marked trails to protect the fragile alpine environment; smoking and cooking outside designated areas are prohibited.
