Drive4it
I am a regular on the route (minimum once a month) but from Man, but route is as Flyinthesky describes. The return is normally the same,though I have returned over Saudi/ Jordan/ Lebanon,and then up to Turkey on a couple of occasions,though not within the last 12 month's. Ground Topography over Iran in daylight is quite striking if you are into that sort of thing.
Interestingly we often used to come back up over Lincolnshire / West Yorkshire to Man but now always come in over Essex,and then up the country. I have asked about the change but never been able to find out what has caused it. Enjoy CMB,I am there myself in early December.
Regards
Mr Mac
