Hwangryonggul – Korea’s Mysterious Cave
Deep in the lush mountains of Samcheok, Gangwon Province, there lies a hidden world beneath the earth—a realm of glittering stone, ancient silence, and geological wonder. This place is known as Hwangryonggul (황룡굴), or Hwangryong Cave, and it is one of South Korea’s largest and most mysterious limestone caves.
Often overshadowed by its more famous sibling, Hwanseongul, Hwangryonggul remains relatively unknown to casual tourists. Yet those who visit it often speak of the experience as otherworldly, almost spiritual—a journey into the veins of the mountain itself.

-
🚗 Access: Typically reached via shuttle bus from Hwanseongul, or a hiking trail through forested mountain paths
🥾 Visiting Hwangryonggul is an adventure—it requires a bit of hiking and guided tour access only. But that’s exactly what preserves its untouched beauty.
2. A Natural Cathedral Beneath the Earth
Hwangryonggul stretches over 6.2 kilometers in total length, making it one of the longest limestone caves in East Asia. Unlike more developed tourist caves, this one remains in its natural state, with minimal artificial lighting or walkways.
Inside, you'll encounter:
-
Towering stalactites and stalagmites formed over tens of thousands of years
-
Underground lakes and reflective pools
-
Rare cave life including blind fish and insects
-
Bizarre rock formations resembling dragons, monks, or waterfalls
The name “Hwangryong” means Yellow Dragon, a nod to local legends of a dragon spirit believed to guard the cave’s inner sanctum.
3. A Protected Cave with Restricted Access
Hwangryonggul is not a walk-in cave. In fact, it is designated as a Natural Monument of Korea (No. 178) due to its scientific and ecological value. Only a limited number of visitors are allowed per day, and a trained guide must accompany every group.
This policy helps:
-
Preserve the fragile limestone structures
-
Prevent damage to cave-dwelling species
-
Maintain air purity and water quality inside the cave
⚠️ Visitors must wear helmets, headlamps, and proper hiking shoes. Prepare for slippery paths and narrow corridors.
4. Myth, Mystery, and the Yellow Dragon
According to local folklore, the cave was home to a yellow dragon who could control rain and wind. The villagers would pray near the cave entrance during times of drought, believing the dragon would answer their pleas with rain.
This blend of spiritual belief and natural awe still lingers today. Some say they feel a strange energy near the underground waterfalls or hear faint echoes of whispers within the dark chambers.
