Are any of these routes going near to a place where you live? If they are, I am always in need of a friendly place in which I can recharge my phone (it's my camera, my sat nav, and my music!), & I would also be grateful for a slither of garden on which to pitch my tent!
Day 1 - John O'Groat's to Invergordon (97 miles)
Day 2 - Invergordon to Altnafeadh (115 miles)
Day 3 - Altnafeadh to Douglas (via Kilbarchan) (121 miles)
*I shall be taking a slight detour, to the village of Kilbarchan. For in that village lives a most welcoming family (the Seeth's), who just so happen to own a lovely little tea shop (Bobbin's!).
