Twenty years from now you will be more disappointed by the things you didn't do. So throw off the bowlines,sail away from the safe harbour. Catch the trade winds in your sails. Explore. Dream. Discover. – Mark Twain
Seven Things for mature visitors to do in Athens in September
On your first full day use the Hop On Hop Off Bus to get an overview of the city and acclimatise yourself to the temperature …it will still be very hot during mid day, it hovered around the 32c mark when I visited.
Plan to visit the ancient library, agora and Roman agora on the same day as they are close together and also near a hop on hop off bus stop.
Wander the streets of Athens taking care of belongings. Explore the narrow alleyways in the Plaka district.
