If you're planning a bit of sightseeing head to Coricancha— just one of the monuments in Cusco Historic Center. Why not live the cultural experience and visit the cathedral, museums, and churches in the area— your sightseeing tour starts here.
If you like strolling among the stalls, you might want to head out to San Pedro Market in Cusco Historic Center and take in the atmosphere. Splash some more cash at Santiago Plaza, Cusco Craft Center, and Calle Marquez.
