As another challenge virgin many thanks for the extra info here.

I've finally plumped for a Knoydart start. Never been there before unless you count a drive to Kinlochhourn (back in in the seventies!) and an incredibly wet day doing geology in Glen Dessary (also in '70s)

Despite some Googling I had not spotted the Sea Bridge option. could make my travel plans more feasible as I'm coming all the way from the soft south of England by train.

cheers
