Tianhetan is a pleasant cave, canal and waterfall park in Huaxi township. The park includes flooded caves which guides take you through in boats, canals which weave through minority farm areas and a spectacular cascade through a narrow opening in the mountain. Following the trail into the mountain leads to a massive sinkhole and the starting point for the cave and canal boat trips. Admission to the park is very reasonable although you will pay extra for the zip line across the gorge.
