Bolivia’s strange curiosities are not confined to La Paz. Only a few hours north is Lake Titicaca, the highest navigable lake in the world, which gave birth to the Inca empire. In the southwest of the country, near a train graveyard, is the Salar de Uyuni, the world’s highest and largest salt lake – 12,000 sq km of blinding white nothingness. South of the salt lake is a Salvador Dali landscape of deserts, volcanoes, bizarre rock formations, bubbling geysers, peculiar green plants and a blood-red lake filled with flamingos. East from here is a hollow silver mountain, dinosaur footprints, villages where annual festivities revolve around ritualized fights and national parks that are so isolated they’re almost impossible to get to.
