Cusco
The Department of Cusco is without a doubt one of the most visited departments in Peru and South America in general. Cusco serves as a gateway to the Andean Mountain Range, Aguas Calientes, which is home to Machu Picchu, and the once capital of the Inca Empire, Cusco. In Cusco, you will experience not only the heart of Peru but the heart of the once-powerful Incan Empire and face the dilemma of whether or not to eat the local delicacy of cuy.
