Regular readers might remember my desire to walk Iceland, because there's 'nothing there'.
I've been doing a bit of research. And the nothing that's there is, as I suspected, very spectacular nothing. Black volcanic sand desert. Unfettered fierce winds. Huge sheets of water. The kind of nothing that represents an existential challenge.
And it is indeed possible to walk Iceland from sea to sea. Michel Blomgren has done it, north to south, and his excellent video documentary "The Iceland traverse" confirmed me in my aspiration to walk Iceland this summer. Warning! Not for the squeamish! (Blisters.)
