The city hangs from the walls of a canyon at 3,650 meters: the highest capital on the planet. You ride the Mi Teleférico cable car and see it whole — a sea of brick houses climbing the mountain with the snow-capped Illimani behind. Below, the Witches' Market sells ancestral remedies and offerings, and the air smells of street food. La Paz isn't a city you stroll through: it takes your breath away, in every sense.
