If we are to believe the interview by Lindsey Fraser (May 2000) then  
this is what Jo said about the location of Hogwarts:

--
Hogwarts School of Witchcraft and Wizardy was the first thing I 
concentrated on.  I was thinking of a place of great order, but 
immense danger, with children who had skills with which they could 
overwhelm their teachers.
Locically it had to be set in a secluded place, and pretty soon I 
settled on Scotland in my mind.  I think it was in subconscious 
tribute to where my parents had married.
People keep saying they know what I based Hogwarts on - but they're 
all wrong.  I have never seen a castle anywhere that looks the way I 
imagine Hogwarts.

So... all we really know is that it is in Scotland - and that in 
reality it does not exist.
