We had a great time and it was a good excuse for me to take in a couple of Who activities, one in either county, that I would not normally get the chance to visit.
Before setting out, I had taken a look on doctorwholocations.net and put in the postcode of where we were staying in Devon, and found that Hound Tor was relatively not that far away.

Hound Tor had been the main location for the classic Tom Baker episode, The Sontaran Experiment. I remember seeing it when it was first screened, and always liked it for its short story approach to a Who tale. Little two-parters don’t come along often, and it was the first I had seen in my Who watching experience, besides, anything to see the original Sontaran actor, Kevin Lindsey giving the seminal performance is always worth a watch.
I had always pictured the location used as a distant, remote spot, high in the Dartmoor hills, and not easily accessed. Though it is true the approach is through winding narrow roads, if I had thought about it, the BBC would not have picked it for an outside broadcast, video-shot episode, if they could not get their equipment within easy reach. A look on GoogleMaps shows the Tor and how close it is to the nearest road, as well as a car park close by (see below © google).
