The Acropolis Museum is an easy walk downhill from the Acropolis and it makes sense to do one after the other if you have the time. During the summer season (1 April – 31 October) tickets cost €15 and can be bought in advance but as I didn’t know how long I was going to be at the Acropolis I settled for buying when I was there. Do note that your bag goes through an x-ray scanner at the entrance and large bags will have to be placed in the cloakroom.
