If you have some additional time during your time in Peru, consider an extension to magical Puno. The train ride will be the perfect way to admire all the changes in nature and landscape, starting in Cusco. Arrive at the shores of the Titicaca, the highest navigable lake. Experience a complete immersion to the local culture of Uros, and ancestral society. Savor the delicacy of the Quechua language and learn a few words before your trip back home.
