Tam Cốc – Bích Động is a popular tourist destination in north Vietnam and part of the Tràng An Scenic Landscape Complex UNESCO World Heritage site.

It consists of two distinct attractions: Tam Cốc, a flooded cave karst system; and Bích Động, a series of mountain temples.

[2][3] Tourists are taken in small boats along the river from the village of Ván Lám, through rice fields and limestone karsts, through the caves, and back.

Local women serve as guides and attempt to sell embroidered goods to their passengers.

Guided tours generally cover historical points and end with a view from the top.
