Bich Dong is a stunning temple complex at the base of high cliffs about 2km (1 1/4 miles) past the starting point for boat rides to Tam Coc. A pond is near the entry, and the main temple courtyard gives way to a series of pagodas along the short path up the high rocky hillside: a good vantage point over the surrounding countryside. Note: At this sacred place, as at other temple sites, it's best to be well behaved and stay covered up (no shorts), even though no one officially checks or enforces a dress code
