On a blog I follow there is a blog post (http://www.iwalkalone.co.uk/?p=38699) about walking along the Itchen Navigation, from Southampton to Winchester.
Intrigued, my Google search led me to these links about the Itchen Way, a walk from Southampton to Winchester and beyond:
I also found a second-hand paperback from 1990, Exploring the Itchen Way by Richard Kenchington, which I’ve just ordered from Abe Book. Perhaps I’ll make the effort to walk the Itchen Way or the Itchen Navigation, in the spring….
I also follow “I walk alone” she and Commando are so active around the area with great photos of the unusual or neglected and always with useful snippets of info to hand.
