I don't know about the age limit, but I suspect they are being cautious 'presuming' those 65+ may have health issues. I was there in my early 50ths and the heat was so oppressive, I had to head back from the ruins. I kept feeling like I was about to pass out with heat stroke. SO, I'm thinking that could be the issue. Being very fair skinned, heat knocks the daylights out of me. But it's a shame if that's their reason as everyone is different. Erika
