Rocio is right. They charge an exaggerated fine. And if you don't pay it, they won't let you out. They told me that if I wanted to leave without a Colombian passport, I had to report to my country. Well I had to pay
If you are a Colombian you must enter Colombia with a Colombian passport or they charge you a fine Alticima. Only to return to the USA do you use your American passport.
I went THAT way last year and it was horrible. I do not recommend traveling without the Colombian. The laws changed there and one without an idea here!
