To buy the Combo ticket, on the home page:
Click on “Acropolis & Slopes”
On the right, select the date and click Continue.
Select the Time Slot and click Continue
Two choices are displayed:
SINGLE-USE for access only to the Acropolis and slopes
COMBINED for access to the Acropolis & Slopes + 6 other sites (list displayed by clicking on ? )
Click on the “Choose your Tickets” button corresponding to your choice and select the number of tickets
Please note that new rules have come into force since September: It is now theoretically mandatory to use your ticket at the entrance to the Acropolis (and only the Acropolis) at the time of your selected time slot +/- 15 minutes.
In my opinion there will be a tolerance at least at the beginning but that is only my opinion. It has no official value.
With the Combined ticket, for Non EU youth aged 6 to 25, it's not possible to buy reduced price.tickets
This reduction is only possible with the Single Use ticket.
If you buy a discounted ticket you will receive a purchase confirmation number with which you must go to the ticket sales counter and present your passport to prove your age.
There are generally fewer people at the side entrance, the one located in the South East near the Acropolis Museum.
In the future, the establishment of designated fast lanes for organized tours and cruise passengers is planned. I don't know if these new access methods will change the length of the queues at the entrances.
In the coming weeks entry will be free:
The last weekend of September (European Heritage day)
October 28 (Ochi Day)
Every first Sunday of the month from November to March
