If you just head to the Atlas just to go up and down Toubkal, its not that great a climb. Longish scree type track that only gets onto a ridge near the top. The views are, though, very good. However, if you include it as part of a longer trek in the area, it can be wonderful. We did it at the end of a week's circular trek in the area, which was one of the best trips I've done.
We also did it to arrive on the summit at sunrise, which might involve a little local knowledge to do in the dark but is pretty straightforward. Being acclimatised by then definitely helped. Sunrise from the top, over the rugged, arid Atlas, with the sun rising over the sahara to the east, and the shadow of the mountain reaching out over the plains of Marrakech, was truly gobsmacking.
