There’s something inherently captivating about waterfalls. The way water tumbles over ancient rock, carving out landscapes and filling the air with its rushing sound, feels timeless and awe-inspiring. In Bannau Brycheiniog, waterfalls are more than just natural wonders—they’re windows into the heart of this wild and beautiful region. 

From cascading ribbons hidden in lush gorges to thunderous torrents spilling into deep pools, the waterfalls here are as diverse as the landscape itself. Whether you’re a keen walker, a photographer in search of that perfect frame, or simply someone who loves immersing themselves in nature, Bannau Brycheiniog offers a wealth of unforgettable falls to explore. 

In this blog, I’ll take you on a journey to my favourite waterfalls in the area—some well-known, others a little off the beaten path. Each one has its own charm, a story to tell, and a unique way of connecting you with the wild beauty of this special place. So lace up your boots, grab your waterproofs, and let’s chase some waterfalls! 

Sgwd Ddu 

Sgwd Ddu is the very definition of a hidden treasure. Rarely visited and completely undetectable until you’re practically on top of it, this secluded waterfall is a peaceful retreat far from the beaten path. Surrounded by the rugged beauty of the mountains, it offers a sense of tranquility that’s hard to find elsewhere. 

If you’re someone who thrives on exploration and loves venturing off the trail, this route is for you. But Sgwd Ddu isn’t just about its serene beauty—it’s also a place steeped in history. 

Just a short distance away lies the crash site of Wellington MF509, a World War II bomber that met a tragic fate on November 20, 1944. The aircraft, on a routine cross-country exercise, encountered engine trouble and flew into heavy shower clouds. Ice began to build up on the wings, and with insufficient power from the remaining engine, the plane lost altitude and crashed into Garreg Goch. All six crew members, young Canadian airmen, lost their lives in the accident. 

For decades, the families of the airmen knew little about the crash’s exact circumstances or location. Then, in 2005, a photograph of one of the airmen—found at the site in 1944—was posted online in an effort to identify him. With the help of McGill University in Montreal, Canada, the families finally learned the full story of their loved ones and the plane, bringing closure to a mystery that had lasted more than 60 years. 

Visiting Sgwd Ddu isn’t just a journey into the wild; it’s a poignant reminder of the past, where the beauty of the natural world meets the weight of history.

Henrhyd Falls 

Henrhyd Falls is by far my favourite waterfall in the park. At an impressive 90 feet, it holds the title of the tallest waterfall in South Wales. Nestled on the western edge of the Bannau Brycheiniog within the lush Graig Llech Woods, it’s a dramatic and awe-inspiring sight. 

But Henrhyd Falls isn’t just known for its natural beauty—it also has a surprising connection to the silver screen. Did you know that the entrance to Batman’s Batcave is right here in the Bannau Brycheiniog? It might not be a well-kept secret, but it’s still thrilling to know that this waterfall played a starring role in The Dark Knight Rises. 

When you watch the film, look for the moment when Robin discovers the Batcave—that scene was filmed at Henrhyd Falls! Standing in front of this cinematic backdrop, it’s easy to imagine yourself stepping into the world of Gotham’s caped crusader. 

Whether you’re a film enthusiast, a waterfall lover, or both, Henrhyd Falls combines natural wonder with Hollywood magic.

Sgwd yr Eira 

Arguably the most famous waterfall in Bannau Brycheiniog, Sgwd yr Eira earns its name—the “Fall of Snow”—from the way its tumbling water cascades like a snowy veil into the pool below. This breathtaking waterfall is a highlight of the popular Four Falls Trail, which also includes Sgwd Clun-Gwyn, Sgwd Isaf Clun-Gwyn, and Sgwd y Pannwr. At approximately 9 km, the trail is a rewarding adventure through some of the park’s most stunning scenery. 

What makes Sgwd yr Eira truly special is the unique experience it offers: you can actually walk behind its spectacular curtain of water. Once used by herdsmen to guide sheep and cattle across the river, this path now allows visitors to experience the waterfall from an extraordinary perspective. The sound of the rushing water and the cool mist on your skin make it an unforgettable encounter with nature. 

As with many places in the Bannau Brycheiniog, Sgwd yr Eira is surrounded by myth and legend. The rocky gorge below the falls, known as Devil’s Glen, is said to be home to otherworldly folk, from mischievous fairies to wandering ghosts. Whether or not you believe in the tales, the mystical atmosphere of this enchanting spot is undeniable. 

 Combining natural beauty, historical intrigue, and a touch of folklore, it’s not hard to see why Sgwd yr Eira is one of the top waterfalls of Bannau Brycheiniog.

 Sychryd Falls 

 Nestled along the Afon Sychryd, Sychryd Falls may not have the grandeur of some of the park’s more dramatic cascades, but what it lacks in scale, it more than makes up for in charm. A picturesque wooden bridge crosses the falls, adding a whimsical touch that feels straight out of a fairytale. 

Below the falls lies the enchanting Pwll y Berw, a hidden canyon pool framed by moss-covered limestone walls and shimmering emerald waters. This magical spot exudes tranquility and invites visitors to pause and soak in its serene beauty. 

Whether you’re drawn by its photogenic charm or looking for a peaceful retreat, Sychryd Falls is a destination that never fails to delight. It’s a place that proves sometimes the smaller, quieter corners of nature hold the greatest magic.

 Sychryd Cascades 

 If you’re up for a bit of adventure, the Sychryd Cascades are calling your name. Here, you can experience the thrill of scrambling up a waterfall, immersing yourself in the rugged beauty of the area while following in the footsteps of history. 

This stretch of the Afon Sychryd, near Dinas Rock, offers more than just natural beauty. A few decades ago, this area was a bustling hub of mining activity. As you make your way along the river, you’ll pass remnants of its industrial past, including the Dinas mines, abandoned tunnels, and the remains of a tramway that once transported materials through the valley. While much of it has been reclaimed by nature, you can still spot traces of this bygone era, adding a historical layer to your adventure. 

One of the highlights of the cascades is scrambling up the very spot where an aerial ropeway once stood, carrying heavy loads across the river. Today, it’s a hands-on challenge for those who love getting closer to the elements and enjoying a more interactive way to explore the falls. 

 The Sychryd Cascades combine adventure, history, and natural beauty, making them a must-visit for explorers who don’t mind getting their hands—and boots—a little wet.

Sgwd Gwladus  

Many of you may have visited Sgwd Gwladus, also known as The Lady Falls, but do you know the tragic love story behind its name? 

Gwladus was the youngest of 24 daughters of King Brychan of Brycheiniog, a 5th-century ruler. She was also the sister of Saint Dwynwen, the Welsh patron saint of love. Among all the princesses, Gwladus was the most beautiful—her golden hair shimmered in the sunlight, her skin radiated health, and her innocent smile warmed the hearts of all who met her. 

Each day, Gwladus would visit the river to bathe, dreaming of true love. It was there she met Einion, a humble peasant. Despite their different social standings, the two fell deeply in love, spending their days laughing and talking by the water. 

Determined to marry Gwladus, Einion approached her father to ask for her hand. But the King refused, unwilling to allow his daughter to wed a commoner. Heartbroken, Gwladus begged her father to reconsider, but her pleas fell on deaf ears. Devastated, she ran to the river, unable to imagine life without Einion. Before he could stop her, she threw herself into the rushing waters, choosing death over separation from her love. 

As the river roared and swept her away, it left behind a magnificent waterfall—a lasting reminder of her tragic fate. Einion, stricken with grief, paced the riverbank, calling out her name. Finally, he too plunged into the river, unable to live without her. The river roared once more, and a second waterfall appeared above the first. 

Though their lives ended in sorrow, it’s said that Gwladus and Einion’s spirits remain together, entwined forever in the magical waters of the Afon Pyrddin. 

Sgwd Gwladus is just one of the many wonders along the Elidir Trail, which also features incredible falls such as Sgwd y Bedol, Sgwd Ddwli Isaf, and Sgwd Ddwli Uchaf. And for those with a sense of adventure, legend has it that the entrance to the fairy kingdom is hidden somewhere along this trail. 

With its enchanting beauty and timeless tale of love and loss, Sgwd Gwladus is more than just a waterfall—it’s a place where history, legend, and nature intertwine.

 Sgwd Einion Gam 

Sgwd Einion Gam is the lesser-known counterpart to Sgwd Gwladus, completing the tragic love story that echoes through the waters of the Afon Pyrddin. Often referred to as the “secret waterfall,” it is not truly a secret, yet its secluded location keeps it off the radar for many visitors. 

Standing at an impressive 88 feet, Sgwd Einion Gam is nearly as tall as Henrhyd Falls. Its dramatic cliffs, cascading water, and the mesmerising lower pool make it one of the most awe-inspiring and enigmatic sights in Bannau Brycheiniog. Surprisingly, despite being located just half a mile upstream from Sgwd Gwladus, it remains one of the park’s most under-visited treasures. 

However, there’s a reason for this. Reaching Sgwd Einion Gam is not for the faint-hearted. The trail requires navigating two river crossings (with no easy way to get across) and precarious goat tracks along steep, uneven terrain. But for those willing to tackle the challenge, this hidden gem offers an unparalleled experience of serene beauty and mystery. 

If you’re seeking an adventure away from the crowds and want to connect with a waterfall that feels truly wild, Sgwd Einion Gam is a journey worth undertaking. It’s a place where nature feels untouched, and the story of Gwladus and Einion lingers in the air, adding a touch of romance and legend to the effort it takes to get there.

 Blaen y Glyn 

Tucked away in the tranquil Talybont Forest, the Blaen y Glyn waterfalls are a paradise for waterfall enthusiasts. Follow the River Caerfanell upstream, and you’ll discover an array of waterfalls and cascades, each more enchanting than the last. Many of the pools are deep enough for a refreshing dip, making it an irresistible destination for wild swimmers and nature lovers alike. 

The centrepiece of the area is the Blaen y Glyn Waterfall, a striking cascade that steals the show with its dramatic drop. While it lacks a pool at its base, it does have a unique feature—a natural water slide carved by centuries of rushing water. For the adventurous, it’s a playful reminder of nature’s raw power and creativity. 

The waterfalls are split into two sections, each offering its own distinct charm: 

• Blaen y Glyn Uchaf (Upper): Here, higher cascades tumble over rugged rocky ledges, surrounded by moss-covered trees and a lush forest canopy. The magical atmosphere makes it feel like stepping into a fairytale. 

• Blaen y Glyn Isaf (Lower): This section features gentler waterfalls and tranquil pools, perfect for quiet reflection, photography, or simply soaking in the serene beauty of the landscape. 

Whether you’re chasing dramatic cascades, searching for the perfect wild swimming spot, or simply enjoying the peaceful ambiance of a forest walk, Blaen y Glyn is a must-visit destination in Bannau Brycheiniog.

 Pen y Fan 

Did you know that Pen y Fan has its own set of waterfalls tucked away on its north side? These hidden gems are among the best-kept secrets in Bannau Brycheiniog, with streams feeding into the Nant Cwm Llwch from the mystical waters of Llyn Cwm Llwch. 

Perched at the head of Cwm Llwch Valley, Llyn Cwm Llwch is the best-preserved glacial lake in South Wales, a stunning relic of the Ice Age. But like so many places in , it is also steeped in legend. The lake is said to be home to an invisible island that reveals itself only once a year, on May Day, when a magical passageway opens. 

For those brave enough to venture through the passageway, a world of wonder awaits—a breathtaking garden inhabited by fairies. The fairies are said to enchant visitors with captivating music, offer glimpses into their future, and present gifts of beautiful flowers and delicious fruit. But, as is often the case with such legends, there’s a catch: nothing from the island can be taken back to the mortal world. 

Of course, the story takes a fateful turn. One visitor, overcome with greed, hid one of the fairies’ flowers in his pocket. Upon returning to the mainland, the flower vanished, and he was struck senseless. Since that day, the magical doorway has remained closed, leaving the island shrouded in mystery. 

With its hidden waterfalls and the enchanting tales surrounding Llyn Cwm Llwch, this area captures the magic, beauty, and wonder of Bannau Brycheiniog. Whether you come for the scenery, the legends, or the challenge of the trails, Pen y Fan’s north side offers an experience like no other.

 Devils Waterfall, Clydach Gorge 

The Devil’s Waterfall, nestled within the dramatic Clydach Gorge, carries a name as eerie as its surroundings. Unlike the more famous Devil’s Bridge in Ceredigion, this waterfall earned its title because some say you can spot the Devil’s face etched into the rocks below the falls. I couldn’t see it myself, but let me know if you do! 

The waterfall sits beneath a well-preserved 17th-century packhorse bridge, a fascinating relic tied to the area’s rich industrial past. The bridge is a significant survivor of the ironworks that once thrived in the Clydach Gorge, offering a glimpse into the historical importance of this rugged landscape. But take care while exploring here—the uneven ground and steep drops demand caution. 

Beyond its industrial history, the Clydach Gorge is a place teeming with legends and folklore. Among its most notorious inhabitants is the Pwca, a shape-shifting goblin that takes the form of various animals—always black—such as a rabbit, horse, or goat. It’s said that encountering the Pwca would bring terrible misfortune, making it a figure both feared and respected in local lore. 

The Gorge is also whispered to have been a gathering place for witches, who brewed their potent concoctions using the rare plants that grow in its shadowy depths. Some even claim that the mystical properties of the Clydach Gorge inspired William Shakespeare to write A Midsummer Night’s Dream. With its enchanting atmosphere, it’s not hard to imagine this magical place as the backdrop for one of the Bard’s most whimsical tales. 

The Devil’s Waterfall and the surrounding gorge blend history, folklore, and natural beauty into an unforgettable experience. Whether you come for the legends, the industrial heritage, or the rugged charm of the landscape, Clydach Gorge has plenty of mysteries waiting to be discovered.
