MüzeKart covers hundreds of Turkish museums and archaeological sites, but some high-interest sections require a separate ticket. Plan the true visit cost before arriving.
The official MüzeKart product page says the card is valid at more than 350 museums and archaeological sites but lists exclusions including Topkapı Harem, Aya İrini, Ephesus Terrace Houses, Göreme Open Air Museum's Dark Church, Sedir Island and the Cinema Museum.
