Hey, just replied to your other post before seeing this one. I intend to go to Esfahan for a day or two and head to the Caspian on about 13 or 14 Nov. Not sure what to do when I get there. Wouldn't mind a bit of seaside camping. Making it up as I go along.
On the weather, 3 degrees celcius (after raining) as I crossed the desert leading up the snow-covered mountains between Shiraz and Yadz. Don't go that way if you've not got the gear. Or make sure you do it slowly during a clear morning. My back wheel slid a few times on the slimy road coming down the first range into the desert. I don't think they get much rain around there.
