The park is situated at the confluence of the Nanshi and Xishi rivers, which feed into the larger Xindian River system.
The name 'Red River Valley' (Honghegu) is derived from the reddish hue of the local sedimentary rock formations along the riverbed.
The area features a well-known suspension bridge that offers a high-vantage point over the river gorge.
It is a recognized habitat for several endemic bird species of Taiwan, including the Formosan blue magpie.
The water clarity is maintained by the upstream protected mountain catchment areas of the Wulai forests.
Red River Valley Park is a scenic riverfront area located in Wulai District, featuring the turquoise waters of the Nanshi River. The site is characterized by massive rock formations, a suspension bridge, and forest trails leading into the mountains. It serves as a popular natural retreat for locals seeking swimming and water-based recreation during warm months. The area is part of the Wulai regional ecosystem, known for its indigenous Atayal cultural history and natural hot spring geography. Visitors primarily access the area via hiking trails that traverse the riverbank and connect to nearby mountain paths.

Wear water-appropriate footwear with good grip, as the river rocks can be extremely slippery.
Bring your own supplies, as there are limited facilities directly within the park boundaries.
Monitor local weather reports closely, as mountain valleys in Wulai are prone to rapid water level rises during rain.
Do not enter the river when water levels appear high or after heavy rainfall due to the risk of flash floods.
The trails and river access areas are occasionally closed following severe typhoons or monsoon weather for safety maintenance.
Practice 'leave no trace' principles; do not litter or use chemical soaps in the river.
