Excavations at the site have revealed stone arrowheads and pottery shards dating back to the Paleolithic and Neolithic periods.
The cave is formed from limestone, typical of the Karst topography found in parts of the Chungcheongbuk-do region.
Cheongseokgul is officially designated as the first of nine distinct scenic spots collectively known as Okhwa 9-gyeong.
The interior of the cave remains cool year-round due to its depth and natural ventilation properties.
Cheongseokgul Cave is the first of the nine scenic views of Okhwa (Okhwa 9-gyeong) located along the Dalcheon River in Cheongju. This natural limestone cave is an archaeologically significant site where prehistoric stone tools and fossils were excavated, confirming ancient human habitation. The cave features a cavernous entrance measuring approximately 10 meters in height and 5 meters in width. Beyond the cave mouth, the site connects to a trail leading to the summit of nearby mountains. The surrounding landscape is characterized by steep, rugged rock formations and clear river waters. Visitors can access the cave via a wooden bridge crossing the river. It serves as both a geological monument and a gateway for trekking paths through the Okhwa area.

Wear sturdy hiking shoes with good grip to navigate the uneven and potentially slippery terrain near the cave entrance.
Combine your visit with a walk along the Dalcheon River bank to fully appreciate the Okhwa 9-gyeong scenery.
Avoid entering deep into the cave without proper equipment; stick to the designated observation areas to prevent accidents on slippery surfaces.
Avoid loud noises to preserve the natural atmosphere; do not touch or remove rock formations inside the cave.
