Sgwd Yr Eira

Highlight • Waterfall

Sgwd Yr Eira is the star attraction of the Brecon Beacons' much-loved 'Waterfall Country' walk. Meaning 'fall of snow' in Welsh, it tumbles over the 50 foot (15.2 m) tall cliff like a beautiful veil of water. What makes the waterfall so special is that you can walk behind it for a truly incredible thing to experience. Do take care when walking behind the falls, though, as the path is rocky, wet and slippery. Make sure you have decent walking boots and waterproofs.

Sgwd Uchaf Clun-Gwyn Waterfall

Highlight • Viewpoint

The first waterfall most hikers encounter when exploring 'Waterfall Country' in the Brecon Beacons is Sgwd Uchaf Clun-Gwyn, meaning ‘upper fall of the white meadow’. Comprising two sets of falls, a few hundred metres apart, the upper falls are the highest and thunder dramatically into the River Mellte below. The lower falls are a picturesque series of cascades that flow into the steep gorge below.

Sgwd y Pannwr

Highlight • Waterfall

Sgwd y Pannwr - 'fall of the fuller' or 'fall of the woollen washer' in Welsh - is the lowermost of the three much-loved falls on the Mellte. Like something from a Jungle Book scene, this waterfall is as dramatic as it is beautiful.

Sgwd Gwladus Waterfall

Highlight • Waterfall

This is just a beautiful walking area. If you do the 'full' 20km waterfall walk you can take in most of the waterfalls in this area that are on the rivers Mellte, Hepste and Nedd Fechan. You can start at a variety of points around the route that has car parking namely Ystradfellte, Porth Yr Ogof or Pontneddfechan. Otherwise just do the best sections of the walk.

Henrhyd Falls

Highlight • Waterfall

Henrhyd Falls is the highest waterfall in South Wales and is a breathtaking sight to behold. The stunning waterfall plunges 90 feet (27 m) into a wooded gorge. It is possible to walk behind the waterfall but take care as the rocks can be slippery.

Graig Llech Wood surrounds the waterfall and is home to much wildlife. Keep a lookout for birds such as woodpeckers, tree creepers, warblers and wrens. The damp and heavily wooded gorge is also a haven for mosses, liverworts and lichen. For this reason, it is designated as a Site of Special Scientific Interest (SSSI). The area is managed by the National Trust.

Blaen-y-Glyn Waterfalls

Highlight • Natural Monument

The Blaen-y-Glyn waterfalls are a number of beautiful cascades where the Nant Bwrefwr and the infant Afon Caerfanell spill from the eastern end of the Central Beacons massif. Although beautiful, the gradients here are steep, so exploring the tumbling streams can be strenuous.

Pen-Pych Waterfall

Highlight • Viewpoint

Resembling something which should be found in Iceland, Pen Pych waterfall is a series of cascades which tumble over a sheer sided sedimentary rock face.

The base of waterfall is enveloped by a half amphitheatre cliffs which only adds to the waterfalls impressive appearance.

Theres is no plunge pool at the base of the falls, instead the tallest section spills 21m onto number of boulders which have tumbled from the cliffs above in years gone by.

The path will lead you to a large rocky viewing area to the right hand side of the falls beneath the cliffs. You can climb up to the base of the falls, if you do do that take care as the rocks can be very slippery.

Melincourt Falls

Highlight • Gorge

Melincourt Waterfall is a stunning waterfall in the Vale of Neath. Plunging 79 feet (24 m) into a thick wooded gorge, the falls are breathtaking. The whole area is a designated nature reserve and is home to a great deal of animal and plant life. A short and reasonably well-maintained path leads from the car park directly to the waterfall. Take care as there are unguarded drops and slippery rocks on the hike to the falls.

The view you are most likely to see is from the top of the falls, to the side. There is a rock shelf that provides a good view for this view. In the summer you will also find people jumping off this shelf into the plunge pool below! There are other views that can be reached down a gully and then along a rough path that takes you to river level.

Pwll y Wrach is a waterfall feature on the River Ennig. The river plunges in two separate streams over a lip of hard rock into a pool formed from softer mudstone. It is suggested that the pool got its name from the ancient method of identifying and punishing witches!

Frequently Asked Questions

Which waterfalls in South Wales offer the unique experience of walking behind the water?

You can walk behind the cascading water at several waterfalls in South Wales. The most notable are Henrhyd Falls, the tallest in South Wales, and Sgwd Yr Eira, part of the Four Falls Trail. Both offer a thrilling perspective, but be aware that paths can be rocky, wet, and slippery.

What is the best time of year to visit the waterfalls in South Wales?

The waterfalls are particularly impressive after rainfall, when water levels are high, making the cascades more powerful. This often means autumn and winter offer dramatic views. However, paths can be more challenging due to mud and slippery conditions. For waterfalls with more difficult access, like Sgwd Einion Gam, lower water levels are often recommended for safety.

Are there family-friendly waterfall walks in South Wales?

Yes, many waterfall walks are suitable for families. The trail to Sgwd Gwladus Waterfall from Pontneddfechan is known for its well-made pathway through woodlands. Henrhyd Falls is also considered family-friendly, though caution is advised on the slippery path behind the falls.

What kind of natural features can I expect to see around the waterfalls in South Wales?

The region, especially 'Waterfall Country' in the Brecon Beacons, is rich in natural beauty. You'll encounter ancient woodlands, deep gorges, and river valleys. The damp environments are havens for diverse flora, including mosses, liverworts, and lichen, making areas like Graig Llech Wood (near Henrhyd Falls) designated Sites of Special Scientific Interest (SSSI).

What are some less-crowded or 'hidden gem' waterfalls in South Wales?

For a more serene experience away from the main crowds, consider the Blaen-y-Glyn Waterfalls in the north-east Brecon Beacons, which feature around 20 cascades along a 2-mile stretch. Other options include Pen-Pych Waterfall, Pwll y Wrach Waterfall, and Melincourt Falls.

What is the typical terrain and difficulty for waterfall walks in South Wales?

Terrain varies, but many trails involve uneven ground, rocks, and can be wet and slippery, especially near the falls or after rain. Some popular routes, like the descent to Sgwd Yr Eira, include around 170 steps. Good walking boots and waterproofs are highly recommended for most waterfall excursions.

Are there opportunities for outdoor activities like running or cycling near the waterfalls?

Yes, the South Wales region offers a variety of outdoor activities. You can find numerous running trails, including routes like the Brecon Beacons Horseshoe Ridge Trail, by exploring the Running Trails In South Wales guide.

Gravel biking routes are also available, such as the Talybont-on-Usk loop, found in the Gravel biking In South Wales guide.

What makes the Four Falls Trail in Ystradfellte a popular choice for visitors?

The Four Falls Trail is popular because it allows you to experience four distinct waterfalls—Sgwd Clun-Gwyn, Sgwd Isaf Clun-Gwyn, Sgwd y Pannwr, and Sgwd yr Eira—within a single 5-mile walk. It winds through ancient woodland and gorges, offering diverse scenery and the chance to walk behind Sgwd Yr Eira.

What should I wear for a waterfall walk in South Wales?

Given the often wet and uneven terrain, it's advisable to wear sturdy, waterproof walking boots with good grip. Waterproof trousers and jackets are also highly recommended, especially if you plan to walk behind any waterfalls or visit after rainfall, to stay comfortable and dry.

Are there any historical or cultural points of interest near the waterfalls?

While the primary draw is natural beauty, some areas have historical connections. For instance, Sgwd y Pannwr's Welsh name indicates its historical use for washing wool. Additionally, Henrhyd Falls gained fame as a filming location for the Batcave in *The Dark Knight Rises*.

Can I find food and drink options near the waterfall trails?

Yes, some areas offer amenities. For example, the village of Pontneddfechan, a common starting point for trails including Sgwd Gwladus Waterfall, has pubs and a bistro where you can find refreshments after your walk.

What is the tallest waterfall in South Wales?

The tallest waterfall in South Wales is Henrhyd Falls, which plunges an impressive 90 feet (27 meters) into a wooded gorge. It's also famous for the opportunity to walk behind its curtain of water.

What do visitors enjoy most about the waterfalls in South Wales?
