A valley beneath Daeamsan
Gwangchi Valley follows the slopes of Daeamsan in Yanggu, Gangwon Province. The county's official tourism guide describes an approach branching from National Route 31 towards Inje. It lists the general location as Gaojak-ri, formerly Nam-myeon, Yanggu-gun; confirm current administrative names and the actual entrance using a local map.
A different valley each season
The official description mentions summer visitors, autumn hikers and lodging near the valley entrance. This is an outdoor landscape, not a guarantee of supervised swimming or any particular water level. Fallen leaves, icy winter paths and slippery stream banks require extra care.
Check what is actually open
Older references to inns and eateries do not establish that they are trading in 2026. Current swimming permission, parking, access restrictions, exact opening arrangements and the condition of the approach road remain unverified. Check weather and local notices before entering the stream area.
Nearby Gwangchi Natural Recreation Forest is a separate managed facility; do not assume its booking rules or fees apply to the entire valley.
