Ok si I have seen where thee graybeards camp is but I really don't know how to get to it any help from the stormcloks camp would be a real help to me thanks . Also where do i find the mages guld?

Go to Ivarstead and follow the only path leading up to the mountain - eventually you'll reach Greybeards.

No mages guild per se. Try the College of Winterhold.

bring a horse and go straight up the mountain, that what I do. I have never found the path. Mages guild is in Winterhold at the back of the city, kinda looks like a castle.

Well if you follow the instructions from the quest Way of the Voice a map marker will show to Ivarstead firstly and will change to HH once you arrive there so path to HH is really easy to find.
Going to HH before invitation is pointless anyway beacuse they won't let you in.
