There are so many places to visit near Ephesus, try to stay in the area for at least two days if possible. Of course, the most popular way to spend a day for visitors to the area is a trip to the ruins of Ephesus and the House of Virgin Mary, and many visitors do a day trip to Pamukkale or Aphrodisias from Kusadasi or Selcuk.  It is also possible to do a day tour to Bergama and to Priene, Miletus and Didyma.  I can also help with tours in the Pamukkale area.  Here are just a few of the tours on offer:
