In the forested hills above West Lake, reachable by a pleasant hike, is the striking tiled-roof, yellow-walled Baopu Taoist Temple . The temple’s first hall contains a statue of Guanyin in front of a Yin and Yang diagram; an effigy of Gehong ( 葛洪) – who once smelted cinnabar here – resides in the next hall, behind a fabulously carved altar decorated with figures.
