In reply to waterfall:
Check the food and water very carefully - from my memory shops/pubs are much, much rarer than you would imagine and you'll need to carry rather more than that.
iirc I got surprised, very low on food and was slightly saved by the shop at Fridaythorpe filling station. Still seems to exist.
Apart from that obviously Market Weighton and Pocklington if you divert to there.
Pub in Thixendale, quite possibly nothing from there through to Filey unless you divert off Heslington brow.
Otherwise it's really suitable for this sort of thing. Nice tracks, a few cows in dale bottoms but not bad and so on.
Very pleasing scenery too, although I still can't quite understand why they didn't include Flamborough head!
