This was the Urubamba river - apparently not very full! According to the locals.
We finally made it to the site around 1.30pm and spent the rest of the afternoon touring the site and climbing up and down seemingly endless flights of stairs.
This large stone at the base of the wall has a total of 26 angles!! and is a single block of granite.
I went to the very top of the site and got these great views - the weather was remarkably clear, considering it is the rainy season. It was the first day in a week that it had not rained.
