Cartagena is a city in Bolivar, Colombia. Cartagena is a UNESCO World Heritage site. Today the city hosts intellectuals and plenty of beautiful restored homes among exotic, highly attractive and dynamic plazas, waterfronts and other public spaces. 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. Also is 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. http://wikitravel.org/en/Cartagena_(Colombia)
