There are numerous ruins along the trail, and time is usually built in for exploring. If you have a good guide, you can learn quite a bit about the way the Incas lived.The picture at left is Runkurakay, which is a only a short uphill hike on the morning of the third day, just before crossing the second pass.
Shortly after that, you'll come upon Sayaqmarka, and our guide spent consider
able time walking us through the remnants of this ancient Inca town. You will again see examples of Inca stone work, and learn to tell whether a particular dwelling was intended for the lower or upper classes (hint: the upper classes received stone that was tighter fitting and with no mortar).
One suggestion: take some notes while you are walking. You will see so much, you will forget what everything is. Such is the case with the ruin on the left. I think it is Concha Marca, encountered shortly after Sayqmarka, but I cannot be sure.
