If you are cruising, there is not a great way to get from the Izmir port to Ephesus. Cruise ships offer the same excursion, however, it is much more expensive - and instead of being in a small group, it is a very large group. Our tour with Viator only had about 15 people in it - the guide was great! Ephesus is a MUST-SEE in this area. The site is vast and really amazing. It is well worth the money!
