 Named after a mountain shaped after a reclining woman, the full name is Tha Nguong Khun Nam Nang Non, the great cave and water source of the Sleeping Lady Mountain. Rich in folklore, it's a popular destination for day trippers and adventurous children. It has its dangers as well. People have gone missing in Tha Nguong before, and once monsoon season starts in July, the cave goes from innocuous to extremely dangerous.
