In reply to An Triubhas:
It depends on how tame you want, and how escapable? Sometimes escapable is a bad thing as it gives a get out clause.
For very easy scrambles, I love things like Crinkle Crags, Swirral Edge, Pike of Stickle, Pike O'Blisco, Angle tarn pikes and Harter fell (Duddon), although my favourite is probably Hall's Fell on Blencathra. I think that they are all capable of offering a gentle introduction, and the opportunity for a little bit of harder fun.
Striding edge, Sharp edge and Jack's Rake are also excellent, but do have moments that require commitment and can terrify the timid.
