Flying into La Paz must be one of the most dramatic introductions to a city anywhere! On the short flight from Sucre we looked out of the window at large dusty plain of the Altiplano below us and slowly the outskirts of El Alto, the La Paz suburb which has become a city in it's own right, began to appear. Then the massive peak of Illumani, the highest mountain in Bolivia, the top of which seemed to reach to the same altitude as our plane, loomed into view. Then, below us, the streets and buildings of El Alto seemed to disappear over the edge of a cliff beneath the peaks of the mountains and a valley which resembled a crater or a bowl appeared. Lining the sides of the crater and tumbling all the way to the bottom is the city of La Paz, or Cidade da Nuestra Señora La Paz (City of Our Lady of Peace) to give it it's full name.
