Melincourt Falls (Sgwd Rhyd Yr Hesg in Welsh) seemed to be one of the unsung waterfalls in an area of South Wales known as Waterfall Country. I suspect the reason why this falls wasn’t as well known as the others was that it was not part of the Brecon Beacons National Park. Actually, it was in its own reserve managed by the Wildlife Trust of South and West Wales towards the head of the Vale of Neath. So I’d imagine it kind of fell off the radar for most of the literature let alone tourist itineraries! When I saw the 80ft (24m) waterfall in person, I was quite surprised at how similar looked to the nearby Sgwd Henrhyd!! One that you can also walk behind unknown to most.

South Wales offers a variety of stunning gorges, primarily within the Brecon Beacons National Park. Beyond the well-known Sgwd Uchaf Clun-Gwyn Waterfall in Waterfall Country, visitors also highly rate Henrhyd Falls, the highest waterfall in South Wales where you can walk behind the curtain of water. Another popular spot is Devil's Bridge and Waterfalls, known for its unique triple bridges and challenging walks into the steep gorge.
The canyons in South Wales, especially in Waterfall Country, are characterized by fast-flowing mountain rivers, numerous cascading waterfalls, and crystal-clear plunge pools. You'll find rugged rock formations, natural rock slides, and terrain that often involves scrambling, climbing, and swimming. Some areas may even require rappelling down waterfalls for the full canyoning experience.
Yes, there are options suitable for families. While many gorges offer adrenaline-pumping challenges, areas like Clydach Gorge are noted for providing a gentler environment, making them ideal for introducing children to gorge walking and the natural beauty of South Wales in a less demanding setting. Henrhyd Falls is also categorized as family-friendly, offering a scenic walk to the impressive waterfall.
The best time to visit the canyons in South Wales is generally during the warmer, drier months, typically from late spring to early autumn. This period offers more stable weather conditions, lower water levels (making activities safer), and more comfortable temperatures for swimming and outdoor exploration. Winter conditions can make canyoning challenging due to colder temperatures and higher, faster-flowing water.
The canyons are perfect for a range of activities including canyoning (canyoneering), gorge walking (gorge scrambling), and wild swimming. You can explore intricate river systems, navigate behind waterfalls, leap into plunge pools (like 'Loonies Leap' in Waterfall Country), and discover hidden natural beauty. Scenic walks to impressive waterfalls like Melincourt Falls are also popular.
South Wales' gorges are rich in natural beauty. You'll encounter dramatic waterfalls, deep plunge pools, unique rock formations, and lush, damp woodlands. These areas are often Sites of Special Scientific Interest (SSSIs), home to diverse plant life including mosses, liverworts, and lichen. Keep an eye out for various bird species such as woodpeckers, tree creepers, warblers, and wrens, especially around areas like Henrhyd Falls.
Beyond the main attractions, you can find unique spots like Huntsman's Leap, a narrow, steep-sided inlet eroded by the sea, offering dramatic coastal views and a local legend. The Blaen Taf Fawr Valley also features a small gorge with a waterfall, providing a more remote experience. For river gorges, Wolf's Leap, River Irfon offers another intermediate option.
The region around the canyons, particularly the Brecon Beacons National Park, offers a wealth of other outdoor activities. You can find excellent opportunities for mountain hikes, with routes like the Pen y Fan Summit loop. There are also numerous road cycling routes, including challenging loops through the Brecon Beacons. For those who love waterfalls, dedicated waterfall hikes are available, such as the Ystradfellte Four Waterfalls Walk.
For canyoning or gorge walking, it's essential to wear appropriate gear. This typically includes a wetsuit for warmth, sturdy footwear with good grip (like old trainers or specific canyoning shoes), a helmet for head protection, and a buoyancy aid. Layers of quick-drying clothing under a wetsuit can also be beneficial. Always consider the water temperature and weather conditions.
Areas like Pontneddfechan, a gateway to Waterfall Country, typically offer basic amenities. You can often find car parking facilities, and in nearby villages, there may be local pubs, cafes, and accommodation options. It's advisable to check in advance for specific opening times and availability, especially during off-peak seasons.
The duration of a canyoning or gorge walking experience can vary widely depending on the route's difficulty, length, and whether you're with a guided tour. Shorter walks to individual waterfalls, like the 10-minute walk to Henrhyd Falls, can be quick. More extensive gorge walks, such as the 'full' 20km waterfall walk in Waterfall Country, can take several hours or even a full day. Always plan according to your fitness level and the specific route.
Yes, some canyon areas also boast historical significance. For instance, Devil's Bridge and Waterfalls is not only a natural wonder but also a historical site, famous for its three bridges built one on top of the other, and is even featured in Welsh crime series. The surrounding areas of the Brecon Beacons also have a rich history, with ancient trails and industrial heritage.
