Cheorwon Hantangang Basalt Gorge

About this spectacle

The Hantangang Basalt Gorge near Cheorwon in Gangwon Province is a striking geological corridor carved through ancient volcanic rock. Here, the Hantantan River has cut deep into layered basalt columns, exposing dramatic dark cliff faces that rise from the water's edge. Visitors walking the riverside trails encounter sheer vertical walls of hexagonal basalt, their geometric precision contrasting with the rushing water below. In winter, portions of the river freeze and frost clings to the rock faces, adding a crystalline quality to the already dramatic scenery. Spring brings green ferns and wildflowers to the cliff ledges, while autumn turns the gorge's fringing vegetation amber and red. The area sits close to the Demilitarized Zone, lending it a quiet, frontier atmosphere seldom found in other geological parks. The sound of the river echoing off basalt walls and the sight of columnar jointing on a grand scale make this a genuinely compelling destination for geology enthusiasts and hikers alike.
