i am Colombian and i used to work for the American embassy in Bogota

we used to take a lot of trips to Cartagena with the American diplomats , so i can tell you it safe to go , you will have a wonderful time , the place you are going in the mountains is the tairona park where the lost city is , or at least that is my guess , nothing to worry about , the tour guides know where to take you , so is not really even an issue ,

Cartagena is like biggest tourist city in Colombia , so you will find , people from all over the world

now you are a traveler , same as me so you will not find much difference as far the rest of latin American countries

just do me a favor , when in cartagena go to this restaurants

Creppes and waflles and order a jugo de curuba

el corral order a hamburguesa todo terreno

and enjoy

IF anything , you can always say you are Canadian that one works wellGoing to Colombia have any tips, advice or recommendations?
