We were looking for something spectacular to make the effort worth it . The first of the caves was a sizeable hole in the ground in which there were a few scrubby trees and some rocks . From the smell , it was pretty clear that it was also a nice out of the way spot for ill - prepared tourists to relieve themselves .
What is the reason some tourist 's might be known as " Ill - prepared " ?

 - The got lost without lights

 - None of the above choices .
