An interesting place. Ancient architecture. It won't be interesting without a guide - just ruins. Therefore, be sure to buy a guided tour.
I recommend visiting the Ephesus Museum, there is a very impressive video show, they give you headphones, and there is an accompaniment in Russian. I do not recommend buying souvenirs - it is very expensive. Take water and hats with you. If you go in the fall, keep in mind that in the morning the temperature may be 10°-12°, and by 11 o'clock in the afternoon it will be under 30°.
There is a house of the Mother of God near Ephesus. Be sure to stop by to see!
A spectacular historical place. I spent the whole day walking along these ancient streets. It is a great miracle to plunge into the life of the city, an audio guide to help.
There are many beautiful views .
