I live not so far away from the WW and have walked and wild camped it a couple of times. Water is an issue as it is dry valleys. [/color]
Commensurate with the WW at times I do a day walk on the North Wolds Way as a training walk. Odd times I have been to the pub at Huggate, farms and houses to get water. It is possible slightly off route to treat water from Millington Beck; near Millington Wood could be the closest. There is a small stream and a house near Uncleby. Lots of sheep about so not the best but possible sources.
