The problem is that they could have been taken pretty nearly anywhere at pretty nearly any altitude
Not in the UK they couldn't there are actually mountains in those pictures

as I hiked only 230 miles of the Colorado Trail this year
So do you take a tent with you or are there like hostels along the way ?, 230 miles is a fair amount of hiking Shaggy.

I am actually going out to France in a couple of weeks right in the countryside in the foothills of one of the mountain ranges the Tour de France goes through sometimes, so i hope to do a bit of walking about but nothing quite on your scale.
