It is located at the crossroads of the old Su-hua (Hwy No.9) and Central Cross Island highways (Hwy No.8). This serves as the eastern gateway to the Park. The road through the Gorge is paved and well marked with signage. There is single lane traffic in each direction and many tunnels to pass through and bridges to cross. In some areas the road narrows and alternating traffic have to use the same lane. This is controlled by automatic traffic lights. The road is quite busy with large and small tour buses, as well as individual travelers, bikers and cyclists.
