The gorge displays classic columnar jointing created when the basalt lava cooled and contracted rapidly.
It is part of the Hantan River Geopark, which spans across Pocheon, Yeoncheon, and Cheorwon.
The Hantan River is unique in Korea as it was formed primarily by volcanic activity rather than tectonic movement.
The name 'Munguri' historically refers to the shape of the terrain where the river bends sharply against the basalt cliffs.
The area preserves traces of the Quaternary period, providing significant data on the formation of the Korean Peninsula's topography.
Munguri Gorge is a prominent basalt canyon located along the Hantan River in Pocheon, designated as a UNESCO Global Geopark site. The gorge features sheer, high vertical cliffs formed by ancient volcanic activity when lava flowed into the river valley. Over time, the Hantan River eroded these layers, exposing distinct columnar jointing and sedimentary deposits. The area is integrated into the Hantan River Dulle-gil trail, a walking path that winds along the riverside. Visitors can observe the geological cross-section of the region's volcanic history directly from the canyon edges. The ecosystem here is diverse, characterized by rocky slopes and riparian vegetation.

Wear sturdy hiking shoes as the trail includes uneven, rocky terrain along the canyon rim.
Bring sufficient water and sun protection as the gorge section has limited shade.
Walk the section connecting to the Bireut-gil trail for the most comprehensive view of the vertical basalt formations.
Do not attempt to descend the steep canyon walls to the water level, as it is dangerous and prohibited.
The trail may be closed during periods of heavy rainfall or high flood alerts for safety.
Stay on marked trails to protect the fragile geological formations and prevent erosion.
