Finding the Condor Temple within an area as vast as Machu Picchu is not that difficult.
It's a fair way from the entrance to Machu Picchu, but keep following the paths and you won't get lost, even if you don't have a guide. I went in twice - once with a guide and once without.
The Condor Temple is sign posted, the same way that the Temple of the Sun is.
And it does look a bit like a condor.
This one was rather busy, so I had to wait my turn for photos.
