In reply to mp93899: It depends on where you are starting from of course, but I would prefer Wasdale(Brackenclose) via Mickledore then depending on how keen they are chose an appropriate descent. Shortest is obviously Lingmell col to Hollowstones. Next would be over Lingmell. Third if they have plenty time would be via Broad Crag and Great End to Esk Hause then Sty Head.
Although the plod up Brown Tongue from Brackenclose is a bit of a drag it gets you into a spectacular location, Mickledor is an easy scramble and the route is short thus achieving the top with time and options on your side.
Of course being from the Wasdale side I'm biased, but from the east it's a trudge. It also gives you a great feel for the layout of Scafell and the Pike as individual hills.
