As I have said in other reviews, I am an archaeologist and history buff, so Changchang City is amazing to me both visually and cognitively. I paid 40 Saul for the tour and she was able to answer my countless questions, which was helpful. She also helped me take a lot of cute photos. I spent 140 Saul on tickets and visited the four archaeological sites inside Chan Chan, Huaca del Sol y Luna, Arco Iris and Esmeralda, which are worth visiting.
