Taiyuan Valley is located on the south side of the Dongfu Highway (Provincial Highway 23) between the Alapawan and Marongarong tribal villages. The gorge scenery formed by the erosion of the Mawu River inspired the name. The scenery from Dengxian Bridge to Taiyuan Tribal Village is considered the most stunning. In the magnificent, deep gorge, a powerful stream of clear water gushes through. It is therefore known as "Little Tianxiang", after the renowned Tianxiang in Taroko Gorge.

When driving a car or motorcycle through the valley, you can feel the steep rocky cliff on the sides so close to you. In the fresh air and cool mountain breeze, you can listen to the chirping of birds and cicadas. Upon entering Taiyuan Basin, expansive views of the lush green Coastal Mountain Range emerge. The area is also home to Formosan rock macaques, which can often be seen foraging and playing in the trees, attracting many visitors for observation and photography.
