Guatemala is mountainous, except for the south coastal area and the northern vast lowlands of Petén department. Two mountain chains enter Guatemala from west to east, dividing the country into three major regions: the highlands, where the mountains are located; the Pacific coast, south of the mountains; and the Petén region, north of the mountains. These areas vary in climate, elevation, and landscape, providing dramatic contrasts between hot and humid tropical lowlands and highland peaks and valleys.
Guatemala officially the Republic of Guatemala (Spanish: República de Guatemala), is a country in Central America bordered by Mexico to the north and west, Belize and the Caribbean to the northeast, Honduras to the east, El Salvador to the southeast and the Pacific Ocean to the south. With an estimated population of around 16.6 million, it is the most populated country in Central America. Guatemala is a representative democracy; its capital and largest city is Nueva Guatemala de la Asunción, also known as Guatemala City.
