The name 'Hongryu' translates to 'Red Stream' because the water is said to appear red when sunlight reflects off the rocks at the falls.
The recreation forest is situated within the Yeongnam Alps, a prominent mountain range often referred to as the 'Alps of Korea'.
The upper and lower sections of the forest are separated by a significant elevation change, requiring a specific mountain road transit.
The area is a habitat for various protected species, including the Amur leopard cat in surrounding valley regions.
Sinbulsan Falls Natural Recreation Forest is a government-managed forest retreat located on the slopes of Sinbulsan Mountain in Ulju-gun, Ulsan. The site is divided into an upper and lower forest area, connected by a specialized forest road that requires vehicle coordination. It is primarily known for housing the Hongryu Falls, which features a 33-meter high drop. The facility offers various lodging options including cabins and forest huts integrated into the temperate forest environment. Visitors primarily use this site as a base for trekking the Yeongnam Alps, a collection of nine major peaks exceeding 1,000 meters in altitude. The forest contains diverse vegetation including pine and broad-leaved tree zones. It is operated by the Korea Forest Service through the Forest Trip portal.
