It is approximately 2,700 m 8,900 ft above sea level and has a population of about 100,000 people. Cajamarca has an equatorial climate so it is mild, dry and sunny, which creates very fertile soil. The city is well-known for its fine cheeses and dairy products. Cajamarca is also known for its churches, and hot springs, or Inca Baths. Yanacocha is considered to be the world's second largest gold producing mine, one of several active mining sites in surrounding areas. Most of all, Peruvians remember Cajamarca as the place where the Inca Empire came to an end, since the Battle of Cajamarca along with the capture and execution of Inca emperor Atahualpa took place here.
Because of the high altitude, precautions should be taken. Be sure to take it easy the first day or two in town, drink lots of water and stay away from alcohol and caffeine. Cajamarca is quite cold at night and the sun can be very strong during the day. Bring some sunscreen and some warm clothes. (http://www.wunderground.c...)
