Postojna Caves

I was having fun taking shots like this from the underground train ride, half expecting that the train ride was all there was. Oh no, not at all. That was just the first 15 minutes. Then it was about another 3 hours to walk through the caves.

Excellent value for the money. Probably about the same cost as Carlsbad Caverns, but you get to see probably ten times as much. (Plus you get an amusement park ride coming and going.)
