In reply to Stone_donkey:
I would approach via the A591 and as you enter Wndermere near Booths, park up and walk up Orrest head only half an hour up and down and was AW`s first view of the Lakes, then get back in car and head up Langdale and walk some or all of the Langdale Pikes, still my Daughters favourite walk, good paths, great views and for a first timer plenty of people around to ask the way.
Consiton Old Man by the main tourist path is a bit boring IMHO and not the best introduction to the lakes.
On the way back you could do worse than call in here
