Acropolis of Athens (Greece)
Must see if you're visiting Athens
To get to the Acropolis, you have to climb up a long, winding sidewalk with steps every-so-often. It was not a difficult climb and there are lots of places to stop and rest under shade trees if needed. The only down side to the Acropolis is almost all of the statues and sculptures have been removed and taken to museums. Don't leave Athens without visiting this. And if you have time find a bar or restaurant with a view of it and watch as the sun goes down - outstanding!
