The main scenic spots include 16 places including Tiansheng Bridge, Shuibo Lane, Xiaochuanyan, Xieyang Valley, Ambergris Wall, Mishai Village, Liupu Cliff, Baimian Village, Baiyun Temple, Neolithic Sites, and Dog Head Stone, covering an area of approximately 9.77 square kilometers. The lower reaches of the basin stream are embedded in the meandering canyon section, where the downcutting erosion and gravity collapse of flowing water are obvious. Danxia boulders collapsed to form the Tangjiaba Tiansheng Bridge, a single-hole stone bridge. The span of the bridge is 64 meters, the arch height is 20 meters, the bridge deck is 14 meters wide and 5 meters thick. The Ou cave whirlpool at the bottom of Shuibo Alley shows that during the intermittent slow uplift of the earth's crust, the downcutting effect of water flow along the rock formation is greater than the side erosion, and it reaches a local erosion base level. Tangjiaba is located in a deep meandering section of low mountain ranges, and the valley wall is in an etched and carved shape.
