Anyone know the location of the Chris Harris Drives Aston V12 vs Porsche 911R was filmed?

I was watching the Aston V12 Vantage vs Porsche 911R video yesterday and the roads on that video look incredible. I assume that these are somewhere in the UK, Wales at a guess.Does anyone know where this is? It's totally for selfish reasons as I want to go out driving there!
