The city was the first Spanish colony on the American continent and one of the first sanctuaries of freed African slaves in the Americas. It is currently populated by an ethnic mix representative of Colombia’s own variety.
Cartagena, located on Colombia’s northern coast and facing the Caribbean Sea, is the most visited city in the country by tourists. It gets extremely crowded in the December holidays and the holy week, when schools are out and most Colombians take their vacations. The city has basically two main parts where tourists go: the walled colonial city (“ciudad amurallada”), which is truly amazing and has many fancy restaurants, clubs and hotels; and a long strip of hotel towers and condos fronting onto the beach, known as Bocagrande. It is also nice to visit the exclusive neighborhood of Castillogrande, filled with recently built condos, places to jog, and a quiet beach to soak up some sun.
