What is the best way to get to the Gap from Gatlinburg, how far, how long (please from someone that has done this, maps do not always tell the whole story)?

Or is there a better way to get there from Sevierville or Pigeon Forge, whatever?

I am planning on riding that way this weekend and want to check out the Gap if I can and if it is not too far from Gatlinburg (seems pretty close).

Any tips welcome. I have already checked out Tail Of The Dragon site (cool).
