Bolivia is a nation in focal South America, with a fluctuated landscape traversing Andes Mountains, the Atacama Desert and Amazon Basin rainforest. At more than 3,500m, its authoritative capital, La Paz, sits on the Andes' Altiplano level with snow-topped Mt. Illimani out of sight. Close by is glass-smooth Lake Titicaca, the mainland's biggest lake, straddling the outskirt with Peru.
