Decent spot. we paid 35Q to camp and bargained our way into going to see just the bats without paying. we've seen plenty if caves but standing surrounded by bats was pretty cool.
the Exon station up the road us a much better spot to sleep if you want real bathrooms. they are super nice and they even have showers.
we stayed there on our way out.
