A good traveler has no fixed plans and is not intent on arriving.
Langogne is at the end of this, the Reservoir de Naussac. This was a largely descending road on fast tarmac into Langogne.
I had thought I might stay at Langogne, the town itself looked worth exploring. I went to the tourist office and got some info and cycled out to the campsite. The campsite though was quite a way out of town, it was unmanned with no facilities and I just didn't fancy it. I also knew that it wasn't too far, 30km, to La Bastide Puylaurent which has a really nice campsite. One I'd stayed at a couple of years ago. So I left the campsite, went back into Langogne and set off again.
Still following the Allier, down the D906, amazing considering that I'd first picked it up at Nevers, the other side of the Massif Central. I must check the route and direction of it and find out how it gets around the Massif.
