Hantangang River UNESCO Global Geopark

Character

Hantangang River UNESCO Global Geopark follows one volcanic river system across Pocheon, Yeoncheon and Cheorwon. Lava entered the old Hantangang valley during the Quaternary, spread along the existing drainage and built a broad basalt plateau; the river later cut down through that younger rock

Auraji preserves pillow lava formed where molten basalt met water. Baekuiri exposes unconsolidated river sediment trapped beneath later basalt. Jaein Falls cuts through the lava plateau in Yeoncheon, while long columnar-jointed cliffs continue along the Imjin River downstream

That variety is what separates the geopark from a single scenic gorge. Its roughly 1,165 square kilometres also include older metamorphic and sedimentary rocks, faults, Paleolithic archaeology at Jeongok-ri and landscapes shaped by the border region’s military history

The experience

The geopark works as a network of separate geosites spread along the river. Pocheon’s Global Geopark Center is a useful orientation point, but a practical day usually concentrates on one section of the river system

Pocheon combines Bidulginang Falls and Meonguri Gorge with other volcanic and fault-related sites. Yeoncheon adds Jaein Falls, Auraji Pillow Lava, Baekuiri Formation and Jeongok-ri, where geology and human prehistory occupy the same river corridor. Cheorwon carries the broad lava plateau, waterfalls and deep basalt gorge farther upstream

Moving between those areas changes what the volcanic story looks like. A waterfall can show the edge of a lava sheet, a road cut can reveal sediment buried beneath basalt, and a cliff can expose the cooling joints inside a thick flow. The park makes most sense when those stops are read as different pieces of the same river history

History

The Hantangang volcanic field is much larger than the UNESCO boundary, extending roughly 195 kilometres along a fault-controlled corridor from North Korea through Paju, Yeoncheon, Pocheon and Cheorwon

Within the present geopark, the lava interacted with an older landscape rather than covering empty ground. River gravels, pre-existing valleys and older bedrock survived beneath or beside the basalt, while later erosion reopened them in cliffs and gorges. That sequence explains why the geopark includes sedimentary, volcanic and fluvial sites within one system

The area also accumulated a human record along the same corridor. Jeongok-ri preserves important Paleolithic evidence, while natural cliffs and river crossings later shaped settlement, fortification and military movement. The Korean War caused severe destruction, and proximity to the DMZ constrained development across much of the twentieth century

UNESCO designated Hantangang as a Global Geopark in 2020. The designation joined Pocheon, Yeoncheon and Cheorwon under one geological framework, turning a fragmented border-region landscape into a shared conservation and geotourism system

Before you go

The address on this page is the Global Geopark Center in Pocheon, not a single entrance to the entire geopark. A visit works best when one jurisdiction or cluster of geosites is chosen first; outdoor sites, museums and paid trails can follow different schedules and admission rules
