Cerro de Pasco is a fascinating place. It lays claim to be the highest city in the world at 4310 metres (although this is highly disputed), is the poorest city in Peru and has a bloody great polymetal mine slap bang in the middle of it that’s as deep as the Empire State Building is tall. Apparently the mining company even has the rights to destroy the historical centre in order to expand. It is also very cold. When the bus pulled in at 6.00am all the Peruvians were layering up in preparation for an Arctic expedition and there was me in just a shirt. Not fun.
