Fellows, I am sorry to disagree with some of you about Syria's topography. I traveled from Amman, in Jordan, to Damascus by land (by colective taxi, with a couple of bedouins in the back seat) and from Damascus to Palmyra and back in 2000.
The Syrian landscape is quite variated, depending of its proximity to the coast, but there are deserts nevertheless. Moreover, it was winter, so it snowed when I arrived in Damascus and I also saw the desert covered by a thin layer of snow along my journey to Palmyra (several hundred klicks). Unfortunately, I was warned not to take photographs from the bus, so I cannot illustrate my words.
Actually you can find everything you like, except lush vegetation.
Cheers,
Panta
