This is a whistle stop tour of lots of the major sites in Turkey. Starting in Istanbul, going over to Gallipoli, then down the west coast to Troy and Ephesus, going over to Pammukale, then down to the turquoise coast and Kas before going to Antalya, inland to Cappadocia and then finally back to Istanbul. It covers a lot of distance and is pretty full on, but the sights make it all worthwhile. If you like archaeology and history in general then this is great trip. But the optional boat trip on the coast and the balloon ride in Cappadocia are also moments of pure relaxation. In hindsight, I think the trip might be better as a 3 week trip with some more down time. It was pretty rushed sightseeing in Istanbul at the end, though another option is just to add more days on at the end.
