Bolivia - Bolivia sits in the middle of South America, bordered by Peru and Chile to the west, Brazil to the north and to the east, Paraguay to the southeast and Argentina to the south. The geography of this landlocked country is highly diverse, ranging from towering mountains and high deserts to steamy lowlands. The Andes Mountains rise in the west. The vast Altiplano, or high plains, and Uyuni salt flats run through the southwest. The Amazon Basin jungles and cloud forests form the northern and eastern sectors, while the arid deserts of the Gran Chaco spread across the southeast.
