Hi Ton,
I’ve never cycled in Turkey but worked on a pipeline project out there over a few years. Things become increasingly eastern..the further east you go….. East of Ankara feels like a completely different culture. You can forget the idea of all inclusive British holiday enclaves that is for sure!
Some notable places working eastwards (bear in mind these are places I went to of note along a pipeline traversing the country, as it was a pipeline, there was only a corridor that I explored: Gallipoli, Biga,Bandirma, Bursa, Eskesehir (mad student party town it would seem! Feels very western compared with places around it. Ankara, Sivas, Erzincan, Erzurum. Vans is supposed to be very worthwhile (Orhan Pamuk’s Snow).
Also spent a bit of time in Georgia, and that is a fantastic place. Great food….hmmmm Khachapuri….
