I am assuming you mean areas to avoid as in areas where which are unsafe to move around alone, especially after dark and for females, in particular. In Qatar, I know of no such areas. I have driven back home alone from Intercontinental and Ritz to Hilal, at night after 12 and 1 , without any mishap. I have not heard of any incident where people were attacked/kidnapped in Qatar. Of course, I have not ventured into deserted bylanes alone, after dark. In any country, it is prudent to stick to known areas after 11pm. The chances of anything untoward happening will then be minimal.
