A true gem on the Caribbean coast, the port city of Cartagena (Cartagena de Indias) welcomes visitors with its charming old town, colonial buildings, and exceptional beaches. A popular cruise ship stop, many seafarers find themselves honorary Cartagenans, as they stroll shady, cobblestone lanes and gaze upon impressive churches. Must-see attractions here include the dramatic fortress Castillo de San Felipe Barajas, Las Bóvedas Market (once a dungeon, now hosting souvenir stores), and the striking, 19th century Clock Tower Monument.
