I love El Condor, and during my trip to Spain I was hoping to see the remains of the El Condor fortress built for the film. Sadly that was not the case. The area is locked and gated.
As I was not feeling adventurous enough to jump the gate, had already visited five other locations that day, and it was getting late, that is as far as I got. Hopefully I can get in contact with whoever owns this location so I can visit it on a return trip next year.
On the plus side there was a great view of "Western Leone" from this location. You will recognize the McBain house from Once Upon a Time in the West. The rest of the town was built later for other westerns and to cash in on the tourists.
Hopefully I can update this post next year!
