Machu Picchu

You should visit this place at least once. It sits high in the Andes Mountains in Peru and is one of the seven wonders of the modern world. Most people take a train from Cusco and then a bus up a steep road to reach the entrance gate.

Once you are inside, you can walk through old stone rooms and look at the terraces. You will probably see llamas grazing on the grass. Make sure to wear comfortable shoes because there are a lot of uneven stone steps to climb.
