While I was staying in Colombia, in 2010, I kept a separate blog. Two of the posts tell about my trip to Perú, where I went to Lima, Cuzco, Machu Picchu, Puno, Arequipa, Nazca and Huacachina.
Rather than recreating them on this blog, I just refer you to the posts themselves.
It has many pictures! The comment section has been closed down, so if you feel the need, you can just post them here.
