The valley gets its name 'Yongchu' from the legend that dragons resided in the deep, bowl-shaped rock pools found along the stream.
The bedrock features natural water slides created by the erosion of solid rock, which are unique to this specific stretch of the Mungyeong mountain range.
The water depth in the middle tier of the valley remains significant even during periods of low rainfall due to the natural geological basin structure.
The site is part of the broader Sobaek Mountain range ecological zone, which supports several indigenous amphibian species.
Yongchu Valley is a natural geological site located at the base of Dae-ya Mountain in Mungyeong, defined by its distinctive three-tiered rock formation that mimics a dragon's body. The valley is characterized by deep, emerald-colored pools carved into bedrock and dramatic rock channels shaped by centuries of water flow. It serves as the starting point for several popular hiking trails leading toward the summit of Dae-ya Mountain. The site is a protected natural area managed by Mungyeong City, focusing on water conservation and the preservation of the riparian ecosystem. The surrounding terrain is composed primarily of granite, contributing to the clear, filtered water quality that flows throughout the year. It is frequently visited by hikers and nature enthusiasts looking for cool, shaded rest points during warmer months.

Bring non-slip footwear as the bedrock in the valley can be extremely slippery even when dry.
Carry out all waste, as the valley is a strictly managed protected area with no trash facilities on-site.
Visit on a weekday to avoid peak crowds from hiking groups descending from the Dae-ya Mountain summit trail.
Do not attempt to hike the trails surrounding the valley without proper mountain boots, as the path transitions quickly to steep, rocky terrain.
Access may be restricted during the heavy monsoon season or high forest fire risk periods; check local forestry office updates.
Strictly no swimming or wading in non-designated areas; do not remove stones or flora.
