Road to Kentmere stile head over toms howe and down tills hole IMHO
TBH i would park in kentmere and start there though
Steep road climb but a reasonable downhill
the BW over Staveley Head is not worth it IMHO looks good on a map but dont do it. I think it can get boggy but I only tried it once.
Dont know the green quarter route at all
Personally I would do Harter fell – FP if you care – than drop down and hike a bike back up from Haweswater – not that great a descent [ its ok though] iirc but only done it once
The HP plantation may be the bit where you enter to go up to green Quarter
Its obvious on the ground
