九曲洞是中横公路的一大奇观,常为中外游客叹为观止,九曲洞是指曲洞之多,并非刚好九个山洞,沿着立雾溪的峡谷风景线而行,触目所及皆是壁立千仞的峭壁、断崖、峡谷等,令人不得不赞叹造物者的鬼斧神工。vivienvivien

Jiuqu Cave, located in Taroko, was built by digging through the mountains when the Zhongheng Highway was opened in 1955. Due to the cutting of the terrain, a winding corridor is formed here, so it is named Jiuqudong. The Jiuqudong tunnel is 1220 meters long and is a wonder of the Zhongheng Highway.
