Until the 1950s only a trail ran through the gorge. Today the Central Cross-Island Highway runs across the wall of the gorge. Despite its name, the Central Cross-Island Highway is a narrow and winding mountain road with numerous bends. The Tunnel of Nine Turns, is a popular spot that takes drivers dramatically close to the edge of the gorge. This part is now strictly pedestrians only as vehicular traffic is routed through another tunnel.
The Central Cross-Island Highway is listed as one of the most dangerous roads by the website dangerousroads.org because of the rugged and unstable terrain. Heavy rain from typhoons often dislodge soil and rocks onto the highway making sections of it unpassable. Flooding occurs widely both as a result of the increased discharge of the river and as a result of water cascading onto the road from the adjacent cliffs. The area is prone to seismic activity.
As one drives through the gorge, they will encounter numerous tourist spots including a Zen monastery, and an old settlement of Truku aboriginals now with museums and handicraft shops. The gorge terminates at a tiny village of Tiansiang where there is a beautiful pagoda and a temple.
