Take your time walking around the site, there are many places to see and explore. Although it is not necessary, taking a guided tour does provide a deeper insight into the ancient city, its uses, and information on the geography of it. Keep in mind that relatively little is known about the history and uses of the ruins, and some of the stories told by the guides are based on little more than imaginative hearsay.
Sun Gate
Inti Punku – if you've just arrived via the Inka Trail, this will be your first experience of the ruins. Others can backtrack from the ruins along the trail and up the hill. From here you can see back down each valley offering excellent views. It's a fairly strenuous hike probably 1-1.5 hours each way but well worth it. If you catch the first bus from Aguas Calientes and head straight here you may be able to reach it in time for sun to peak over the mountain and through the gate.Temple of the Sun
– Near the summit of the main city, the stonework on the temple is incredible. Look closely and you will see that there are a variety of stone walls throughout the city. Most are rough stones held together with mud, the common stone walls found throughout the world. But many buildings or parts of buildings are done with the more distinctive and impressive closely-fit stonework. The temple is the absolute pinnacle of this technology. Observe it from the side, descending the stone staircase in the main plaza.Intihuatana
– A stone carved so that on certain days, at dawn, the sun makes a certain shadow, thus working as a sun dial. From Quechua: Inti = sun, huatana = to take, grab: thus grabing measuring the sun. pronounce 'intiwatana'Temple of the Three Windows
–Main Temple
–Temple of the Condor
– The tour guides will try to tell you that this was a temple, but look closely: between the wings of the condor is a chamber with grooves cut in the stone to secure manacles, a walkway behind where a torturer may walk to whip the prisoner's backs, and a scary looking pit to let the blood of prisoners drain. Clearly the condor was a symbol of cruel justice, but a sanitized version is told for the benefit of middle-aged tourists and their children.
