In reply to mike123:
Ways I've done this -
Do the ridge in reverse is probably the best way to get back to the start. Double the scrambling for your money.
Return eastwards from Sgorr nam Fiannaidh and follow roughly the burn down to the big lay-by on the a82(not particularly pleasant). Theres a wee path on the other side of the road (or hitch)
Carry on and do the pap and then drop down to the road and walk to Glencoe village where your lift awaits.
When I was in the glen the other week the usual wee parking area looked awfully busy from I assume folk not wanting to pay to park in the refurbished 3 sisters parking.
