Kusadasi is a small city on the coast close to Ephesus. If you are visiting Ephesus, I advise to stay in Selcuk; it’s much nicer and cheaper. However, if you are arriving or departing by ferry or cruise ship, you will end up in Kusadasi.
There are some very large ships in the port. I went down to get a ferry ticket to Greece and see Pidgeon Island, which is nice for a stroll, but it’s nothing too exciting.
There are many many shops around the ferry terminal, so if you like to be harassed by shopkeepers then this is a good place to stroll around! In all seriousness I’ve been told you can get good bargains here, but I just can’t stand shopping when some guy is trying to sell me everything in the store at a “good price”. I’ve ran out of ways to say “No, I don’t want to buy your Turkish carpet” 🙂
