The admission fee to the monastery at Fēixiá, 4km upstream from Fēilái, includes an eight-minute ride (every 15 minutes) to the Taoist relics uphill. Cángxiá Ancient Cave (藏霞古洞; c 1863) is a maze of whispering shadows, abandoned courtyards and crumbling alleys connected by arboured paths. Further up, there is a pagoda; further down, a nunnery.
