One of the most beautiful cities in Peru, with buildings and white colonial houses (nicknamed the White City for its constructions of light colored volcanic rock), wide squares and green areas. Against a backdrop of a mountain range on which stands the gigantic Misti volcano (a perfect cone of 5822 meters), flanked by the Chachani (left) and the Pichu Pichu (right). Its mixture of big and cosmopolitan city (second largest city in the country), on the one hand, and its Andean environment, on the other, makes it very attractive for the traveler. Some of the things you can do in Arequipa are:
Stroll through the colonial center enjoying the churches, convents and mansions
Go out at night
Visit some museums. Two stand out above the rest: the Museo Santuarios Andinos, focusing on different aspects of the Andean culture (the main attraction are the Inca children offered to the gods/mountains, in whose climatic conditions they were perfectly preserved), and the Museo de Arte Virreinal Santa Teresa.
Hiking in the mountains. There are many routes to choose from, among which we can mention the popular ascent to the Misti volcano (bring coca leaves for altitude sickness!). It takes between two and three days to go up and down.
About the Colca Canyon you can visit it with a guide, but I recommend doing it on your own (much cheaper and at your own pace). The road is spectacular, passing through the Salinas and Aguada Blanca National Reserve, the inhospitable altiplano (areas close to 5000 meters), and the descent to Chivay.
