Pyramids, Giza, Egypt
Score: 51

"Lots of money has been spent on conservation recently; however infrastructure, in particular roads, is encroaching on the site until it will become locked in by a completely urban landscape. In other ways, fantastic."

"Needs more control over encroaching city and mass tourism."

Valley of the Kings, Luxor, Egypt
Score: 57

"Another very special area that needs much improved visitor interpretation. Must set carrying capacity or limits of acceptable change."

"Overpopulated, touristy, expensive but acceptable as long as funds are put towards restoration and management of the site. Should control number of tourists."
