Tourism in Colombia is an important sector in the country's economy. Colombia has major attractions as a tourist destination, such as Cartagena and its historic surroundings, which are on the UNESCO World Heritage List; the insular department of San Andrés, Providencia y Santa Catalina; Santa Marta, Cartagena and the surrounding area. Fairly recently, Bogotá, the nation's capital, has become Colombia's major tourist destination because of its improved museums and entertainment facilities and its major urban renovations, including the rehabilitation of public areas, the development of parks, and the creation of an extensive network of cycling routes. With its very rich and varied geography, which includes the Amazon and Andean regions, the llanos, the Caribbean and Pacific coasts, and the deserts of La Guajira, and its unique biodiversity, Colombia also has major potential for ecotourism.
