When you think of Christopher Nolan's films, your mind might wander to the Parisian boulevards from Inception, New York's skyscrapers doubling as Gotham in Batman, or even the expansive New Mexico desert featured in Oppenheimer.

However, for devotees of the groundbreaking British director, one iconic location is much closer to home and it's sure to leave you breathless.

Nestled deep within a wooded gorge on the fringes of the Brecon Beacons, there lies a waterfall so spectacular that it was chosen as a filming location for a major Hollywood blockbuster.

Yet, many Welsh locals may not even be aware of its existence.

Henrhyd Falls, the tallest waterfall in South Wales, was selected by Christopher Nolan as the entrance to the Batcave in his entire The Dark Knight trilogy. Scenes featuring the Black Tumbler - the massive tank-like Batmobile - soaring through the Welsh waters into the superhero's clandestine lair were filmed here, reports the Express.

But fear not, you don't need to be the Caped Crusader to visit this waterfall. There's no need for any of Bruce Wayne's gadgets, perhaps just a sturdy pair of boots will do.

Your journey begins with a walk along a path through verdant woodland near the village of Coelbren. Here, you can already hear the sound of rushing water in the distance.

A steep yet well-maintained footpath then guides you down into the gorge, winding towards the waters.

After a 20-minute stroll, you're greeted by the breathtaking sight of a 27-metre waterfall cascading into a moss-lined gorge.

This might trigger memories of Batman's secret lair from The Dark Knight Rises, as this very waterfall was featured prominently when John Blake, aka Robin, stumbles upon the hidden entrance to the Batcave.

What transforms Henrhyd from just a picturesque scene to a location with Hollywood status is its inherent drama. The waterfall tumbles over a hard sandstone ledge, known locally as the "Farewell Rock", into a narrow gorge enveloped by dense forest.

It's slightly off the beaten path, giving it that elusive "hidden lair" feel.

One recent visitor was utterly captivated by the experience, leaving a glowing review: "Henrhyd Falls is absolutely stunning - a hidden gem surrounded by beautiful nature. The walk down to the waterfall is scenic and peaceful, and standing behind the falls is an unforgettable experience. The sound of the rushing water and the lush greenery make it feel magical."

The optimal time to visit is after a light rain shower, when the waterfall is at its most dramatic, although the paths can be slippery, particularly if you venture behind the curtain of water.

Early mornings are usually quieter, and sturdy footwear is essential - along with a waterproof if you plan to get close enough to feel the spray.

Henrhyd Falls is a must-visit for nature lovers and Batman enthusiasts alike. Even if the Batmobile isn't spotted in the shadows, visitors will undoubtedly leave with the sense of having uncovered one of Wales's most captivating hidden gems.
