Ephesus is a good 30 minutes from the port where you will be docked. You can probably get a cab, but you will not do anything other than see the ruins and not know the history behind what you are looking at.
If you choose not to take a ship excursion to Ephesus, you might consider a private tour guide. Friends of ours have used a guide, Nejat, whose specialty is Ephesus. They have used him twice and rave about him. He can be reached at firstname.lastname@example.org. If you are interested in Ephesus, this is probably the way to go.
we will be in kusadasi, how we can do Ephesus tour, from the port of kusadasi ?
You'll need to do something organized - either ship's tour or private, as the distance is too much for walking, and I'm not sure I'd be totally comfortable with getting a cab at the port there.
We were there on Princess and took the "Elite" tour, which included the Terrace Houses. It was a smaller group - around 15 or so - and had as an 'add on' the archeological excavations underway in the ancient equivalent of waterfront condos - that is honestly what they looked like!
It was really worthwhile and I would strongly recommend that whatever tour you take you make sure they are included. You can really get a strong sense of what everyday life was like and the homes are astoundingly contemporary feeling.
Loved Ephesus, it was one of the highlights of our Med. cruise.
