If you visited Colombia or are from Colombia let us know what are the best places to visit there and why.
Guatape is my favorite place in Colombia. It's relatively close from Medellin and it can be done in one day. Old Cartagena is also very beautiful and worth visiting.
It depends what you like. The cities, except old Cartagena, don't have much to offer but the countryside is very beautiful but it may be dangerous. Also, try to go to Barranquilla during the carnival, you will be surprised.
