The underground caves are worth inspecting in Cappadocia, I got lost in one for a time when the power cut out and I was down there late in the day by myself, not cool! but sure etched into my memory, also Ephesus, Troas down on the coast well worth exploring. Old desolate amphitheatres where man versed beast in gruesome contest, and yes don't forget to get a haircut and cut-throat shave down the alleys in the old city.
