Geographers have devised different ways to divide Colombia into regions. It is most appropriate to divide the country into four geographic regions: the Andean highlands, consisting of the three Andean ranges and intervening valley lowlands the Caribbean lowlands coastal region the Pacific lowlands coastal region, separated from the Caribbean lowlands by swamps at the base of the Isthmus of Panama and eastern Colombia, the great plain that lies to the east of the Andes Mountains.
