Ninthace - I fear a return trip from t'other end may be a wander too far for a day walk for me but it has given me an idea of walking to Dent over Whernside, staying the night, then walking back to Ingleton via your route the next day.
Peter - I like your comment and I may hold you to it seeing as you've dragged me up the other two of the Y3Ps... time I returned the favour
I did send you a PM on Facebook Messenger but I don't think you've seen it.
des65 - Aye, that did cross my mind. It would probably have to be a taxi from Ribblehead as walking from there to Twistleton end scars then up and over Whernside back to Dent is an epic mountain day out for me. My original plan is challenging enough in my world!
Dovegirl - cheers for those links. No I'd not seen them.
Pleb - yes, the bus goes to/from the train station but sadly doesn't go anywhere near Ingleton without a connecting bus from probably Settle.
It's just really frustrating because there's a lovely (albeit narrow) direct route from Dent to Ingleton that absolutely NOTHING in terms of public transport travels down which does surprise me in a way.
