I add some pictures that show the busride from Kahta to Adana, because is shows the kind of landscapes one may see (and some towns).

I had stayed one night in Gölbaşı on my way to Kahta and Nemrut, this is one of some pictures of Gölbaşı as I passed on the way back. The name means "Lake side", but the lake was too far from the centre, and the centre itself, well, nothing worthwhile. My hotel, no stars, no frills.
