By far, Sacsayhuaman is my favorite archaeological site in Cusco. It is located near the main square (1km), and that may be the reason I have written many posts about that site:
In order to visit the site, you will need the Boleto Turístico and it would be better if you read all about it before.
The site of Sacsayhuaman is huge but one place you will not definitely miss either being by your own or part of an organized tour is the so-called Fortress. However, we know now that Sacsayhuaman was a fortress and much more.
In-depth Tour Around Sacsayhuaman:
Atop the walls that form the “fortress” there is a forbidden area which is really impressive even though you only see now the foundations.
To the south of this summit, it is an area that used to be closed for tourists but it has been opened recently. And there is a great view of the city of Cusco from here.
Sacsayhuaman is much more, however. Just in front of the fortress and across the prairie of Chukipampa there is a smaller wall than the fortress but it hides impressive carved stones so you may want to walk alongside this wall.
This wall is just the starting point of the popular Rodadero or Suchuna which is located after the stone staircase.
In case you still have time, you can visit the most northern zone of Sacsayhuaman which is rarely visited by foreigners.
When to Visit Sacsayhuaman:
Actually, Sacsayhuaman is so close to the city of Cusco that you can visit it all around the year. Even the rain season during january to march is not a stop.
However, if you like feasts and typical dances the best moment to go there is on June 24th when the city celebrates the Inti Raymi, the most important feast in Cusco.
One less important yet funny feast which is celebrated in September in this site is the Warachicuy or Raise to Knighthood.
Historical Facts about Sacsayhuaman:
It is said that Cusco has the shape of a puma and Sacsayhuaman was the head of that animal. In addition to being intrigued about this issue, I have always asked these two questions: when Sacsayhuaman was built and above all how the Incas built it.
I guess many of these questions will remain unclear but archaeologists keep on finding new treasures in this site.
Enjoy Sacsayhuaman as much as I do!!!
