It seemed to me to be pretty good, with the caveats that there are inevitably "celebrities" to boost viewing figures while I would prefer "ordinary people" who are usually much more interesting. But a nice combination of walking, religion, scenery, and local people who are great. Having said that, I love Spain and the Spanish so walking to Istanbul (even though much is done by motor transport, obviously) doesn't hold much fascination for me. But a good programme. Recommended.
I look forward to sitting down later today to watch it, as I recorded it. I will not have time till later. I have decided to do the equivalent of a half day camino beginning at 07.30. I will post in the Where did you walk thread later! All conveniences readily at hand, and not even a daypack is required. Just grit, and an upward tilt of the head.
