Arequipa is a UNESCO world heritage site, overlooked by the conical El Misti volcano. It does justice to its nickname, the ‘white city’, as its buildings consist of ‘sillar’, a white volcanic rock that embellishes the facades of the city’s homes and churches. The town of Arequipa is situated at around 2500 metres, making this an ideal stop over between Lima and Cuzco, allowing you to acclimatise slowly to altitude.
