What makes these locations so effective isn’t just the water. It’s the texture. The grit. South Wales has this beautiful, tragic industrial skin—abandoned factories, overgrown railway lines, and a sky that looks like it’s constantly about to sneeze. Filming there gives After the Flood a gritty realism that CGI can’t fake. You can almost smell the damp through the screen.
Plus, let’s be real: if they’d filmed it in a studio lot in London, it would look like a theme park ride. The Welsh locations make you feel like you could step into the show and instantly catch a cold. And that’s a compliment. A damp, shivering compliment.
So, Where Can You Actually Visit?
If you’re feeling brave—and don’t mind the 50% chance of rain—here’s the tourist’s cheat sheet. The quarry scenes are mostly around Blaenavon, the car park is in Cardiff (though it’s probably been knocked down by now), and the brickworks are near Pontypool. Just don’t go expecting a welcome sign. The residents there are used to film crews, but they’re also Welsh—which means they’ll only be politely interested in why you’re poking around a flooded ditch.
And Dave? He’s already planning a trip with his waterproof trousers and a flask. I’ll let you know if he finds the tunnel. But honestly, the best view of Series 2’s locations? Probably from your sofa, with the heating on full blast. Because you don’t need to get wet to appreciate the artistry of a good, soggy set.
