The entrance of the Tunnel of Nine Turns (Jiuqudong) is at 174.5 km along the Central Cross-Island Highway. It was formerly part of the Central Cross-Island Hwy. In 1996 the new Tunnel of Nine Turns was completed， and the original one was converted into a pedestrian trail. From the western entrance to the eastern exit， the length is about 1.3 km. It takes about 40 minutes to traverse each way. The trail is flat and rather broad， but visitors still need to be cautious of falling rocks.Along the trail huge cliffs are a common sight， demonstrating the infinite power of nature. Along the twists and turns， you see the faults and folds on the cliff as well as the clouds lingering at the mouth of the cave. The view is exceptionally enjoyable. The sound of Liwu River crashing into the rocks echoes in your ears.
