This series is probably not the sort that you mean but I have just discovered 'Winter Walks' on BBC4 apparently it was on BBC2 and is now being repeated on 4. Just looking at the views and remembering some of the same or similar walks when I was able is so calming. The contributors/walkers don't say a lot, just enough, and allow the viewer to just lose themselves in the peaceful scenery and non-intrusive words pop up now and again, with Grid references and one sentence or even just a couple of words about the high points. I record it and watch it when I get up in the morning whilst my tablets are taking effect before I can have my breakfast. :-)
As I say probably not the sort of series you mean but I love it. :-)
