The cave is called Hang Sung Sot, which, we were told, translates as "Surprising Cave." The cave contains
such surprising views as the vague likeness of a giant Vietnamese penis in limestone illuminated by a red
spotlight. Sorry, I didn't photograph it, but I did photograph a not very convincing Romeo and Juliet nearby.
The walk through the cave is a one-way loop, with hundreds of steps and this lovely lookout at its highest point.
