Arequipa is Peru's second-largest city and is known as the White City because many of its buildings are made from a pale volcanic stone. Three tall volcanoes stand guard over the town.
Visit the beautiful white cathedral, wander a centuries-old convent painted in blue and orange, and gaze up at the snowy volcano called El Misti.
Near Arequipa is the Colca Canyon, one of the deepest in the world, where giant Andean condors soar overhead.
The white stone buildings glow in the sunshine and make the whole city center feel bright and special.
