I spent a bit of time feeling disorientated in Islamabad - maybe its just me having an inherently bad sense of diretion!
I found that the best way to get your bearings is to work out where the Margalla Hills are (these are the range of hills that run along the Northern outskirts of Islamabad.) Since the area is pretty flat, they work well.
I then remembered where I was by "walking away from the hills', walking with the hills on my right etc etc........
Also, the Shah Faisal mosque is a pretty good landmark - able to be seen from most places.
There a no. of good hotels like Pearl Contonental And Marriot and a no of fast food resturents also
Fondest memory: The Margala Hills are beautiful And you will always remember the greenry of them.
