Mudeungsan National Park

Character

Gwangju spent 57 years looking up at a summit ridge ordinary hikers could not fully enter. A military unit occupied Mudeungsan’s highest section in 1966; in 2023 Inwangbong reopened permanently, restoring public access to one of the mountain’s three summit peaks

Above the forest, the mountain changes material. Seoseokdae, Ipseokdae and Gwangseokdae are giant columnar-joint formations cut into welded volcanic tuff formed roughly 85–87 million years ago. Their unusually high elevation and large columns make the upper mountain look constructed at a distance, even though the geometry comes from cooling volcanic rock

The experience

Mudeungsan works as a network, so the first useful decision is the trailhead and the amount of climbing you want. KNPS maintains several official courses rather than one canonical ascent. Lower routes move through dense forest and temple approaches; longer routes climb toward open grasslands and the stone formations that define the upper ridge

The mountain’s closeness to Gwangju is part of its character. It rises immediately beyond the urban districts instead of functioning as a remote expedition, and local hiking culture treats repeated visits, seasonal routes and shorter forest outings as naturally as summit ambitions. The upper geology rewards a longer day, but the park does not require reaching the highest accessible point to make sense

Inwangbong now gives ordinary hikers a permanent summit-side destination that had been inaccessible for decades. Cheonwangbong and other controlled military sections are a different matter: special summit openings use separate reservation and identification rules. That distinction matters when reading maps or older accounts that simply describe “the summit” as closed or open

History

Mudeungsan’s oldest story is volcanic. Major eruptions in the Late Cretaceous produced welded tuff, and cooling fractures formed the vertical stone columns now concentrated around the upper ridges. The formations later became the geological centerpiece of the Mudeungsan area’s conservation identity

Modern access changed sharply in December 1966, when a military unit entered the summit area and the highest ridge was fenced from ordinary public use. Controlled openings began in 2011, allowing occasional access under special arrangements. The restriction became part of Gwangju’s relationship with a mountain visible from much of the city but only partly reachable at its top

Conservation status expanded during the same period. Mudeungsan became South Korea’s 21st national park in March 2013. The wider area was certified as a national geopark in 2014 and joined UNESCO’s Global Geoparks network in 2018, recognizing a landscape that links volcanic geology to the settlements and cultural history around it

A major access change followed on September 23, 2023, when Inwangbong reopened permanently after 57 years. The highest military-controlled areas did not simply become unrestricted public trail, but the reopening altered the ordinary hiking map: a summit peak that generations of Gwangju residents could see but not freely visit became part of the regular mountain experience

Before you go

Choose the trailhead before choosing transport or estimating time. Mudeungsan is a trail network, and a short forest visit, a columnar-joint hike and a summit-side day require different approaches. Check KNPS entry-time controls and current trail closures before setting out, especially for longer upper routes; do not assume special access rules for the controlled highest summit section apply to ordinary park trails
