My opinion about Zipaquira:
The cave is a bit far from Bogotá so you have to rent a car to go there. While you’re in the car you can look out of the winow and see the nature. The nature there is different than Sweden. I have never been in a real cave, with real I mean a big cave. When we came to the place there were some people who played panpipe, the same melody as ABBA (don’t remember which song). When we came in it was bigger than I expected, it was cold and dark. And there were a chapel as well. You must go there when you go to Colombia!
