We are looking to spending 2 -3 weeks touring eastern Turkey mid May , starting by flying into Trabzon from Istanbul and hiring a car to drive to Ayder and Altiparmak, as a base for the Kackar Mtns, then on to Ani,Lake Van, perhaps dropping the car off at Sanlurfa airport after visiting Mt Nemrut. Any suggestions? How rough are the roads( would a Ford Fiesta be OK?) and is this too much in distance? Suggestions on places we must see are very welcome!
