Trail Introduction

Starting at Swallow Grotto (Yanzikou) on the Central Cross-Island Highway, the Liwu River Gorge narrows until Cimu Bridge in the west. This is the most popular section of the gorge, and visitors can take the Swallow Grotto (Yanzikou) Trail from Swallow Grotto (Yanzikou) to Jinheng Bridge, enjoying views of the gorge, potholes in the rock, springs, and the "Chieftain Profile Rock".

                                   Yanzikou (Swallow Grotto) Trail Map
As of early 2005 the Yanzikou (Swallow Grotto) Trail was separated from the highway by a simple concrete divider. The road was narrow, resulting in frequent congestion in the area. Consequently, the Park Administration set about building a two-lane tunnel for vehicular traffic to let walkers enjoy the sights of this spectacular part of the gorge. There are two Swallow Grotto (Yanzikou) tunnels, linked by Ludan Bridge- were completed in June 1, 2007. West-east vehicular traffic must use the tunnels. The old highway is now a pedestrian path and is also open to vehicular traffic going west (Taroko heading to Tianxiang) only that must proceed slowly. The Swallow Grotto (Yanzikou) Trail has a simple barrier separating the walkway and vehicle lane. However, as the road is narrow, please proceed carefully. 

History and Culture

Jinheng Park is memorial to Jinheng, a supervisor who died during the construction of the Central Cross-Island Highway. The Park contains a bust statue in his likeness, a plaque honoring all those who died during construction, a small souvenir shop, and an observation deck outside the store from which the Indian Chieftain Rock can be best viewed. The Swallow Grotto (Yanzikou) is definitely a trail featuring unique terrain, ecology, and history.

                              Jinheng Park


The Swallow Grotto(Yanzikou), named after the many swallows that forge and play among the rocks, formed over tens of thousands of years. Over millenia, the Liwu river sculpted marble masterpieces such as the Chieftain Profile Rock, and many hollows and potholes that pockmark the grotto. Resembling swallow' s nests, these unique formations lent further inspiration for this grotto's name.
