Sgwd Yr Eira Waterfall Walk: Route Guide + Walk Behind the Falls (Wales)

Sgwd Yr Eira was one of the waterfall walks we did while staying at Poston Mill Park in Herefordshire. It is a quiet countryside base, but one of the main reasons we chose it was its proximity to the Bannau Brycheiniog National Park. We had planned a couple of waterfall trails, and it worked really well as a base for that.

This was the first one we did. We visited Henrhyd Waterfall after this. Both are very different, and we enjoyed each for their own reasons.

Sgwd Yr Eira stood out straight away.

It is not just about seeing a waterfall. You can actually walk behind it. That alone makes it feel a bit more special.

We parked at Dinas Rock Car Park and started the walk from there. What looked like a simple trail turned into one of the most enjoyable parts of our trip.

Where is Sgwd Yr Eira?

Sgwd Yr Eira is part of the popular “Waterfall Country” area in the Bannau Brycheiniog National Park in South Wales.

This part of the park is known for its cluster of waterfalls, all linked by walking trails through woodland and along river gorges. You can easily spend a full day here if you want to explore more than one.

The Sgwd Yr Eira trail starts near Pontneddfechan and is one of the most well-known routes in the area. What makes it stand out is simple. It is one of the few places where you can walk right behind a waterfall.

How to Get To Sgwd Yr Eira

The easiest way to reach Sgwd Yr Eira is by car.

We drove to Dinas Rock Car Park and started the walk from there. The car park is basic but convenient, and it puts you right at the start of the trail.

If you are staying nearby, it is an easy drive:

• From Hay-on-Wye: around 1 hour to 1 hour 15 minutes
• From Cardiff: around 1 hour
• From Swansea: around 45 minutes

The roads are mostly straightforward, though the last stretch gets a bit more rural.

Public transport is possible, but not ideal. You can get close to Pontneddfechan by bus, but you will still need to walk to reach the trail start.

Driving is by far the simplest option, especially if you are planning to explore more waterfalls in the area.
 

Sgwd Yr Eira Waterfall Walk Route

This is a really varied walk. It is not just one type of path. You move through woodland, open sections, and then down into the gorge near the waterfall.

The route is well signposted, and we found it easy to follow throughout.

 

Start at Dinas Rock

The walk begins at Dinas Rock Car Park.

Right from the start, you will see signboards pointing towards Sgwd Yr Eira and other trails in the area. It is quite clear where to go, which makes things simple.

The initial stretch is rocky and slightly uphill, but there is a metal handrail in place to help. The path, however,  quickly leads you away from the road and into a quieter setting and it already starts to feel like you are heading into proper countryside.

Woodland Trail Section

This section is easy and relaxed.

You walk through woodland paths that are wide and well defined. Some parts are flat, while others have a gentle incline, but nothing too demanding.

The scenery keeps changing slightly. At times you are surrounded by trees, and then you get small open patches where you can see further ahead.

You will also start to hear the river now and then. It is not always visible, but the sound follows you along parts of the trail.

River and Gorge Section

As you continue, the walk starts to feel a bit more dramatic.

The path begins to contour above the wooded valleys, with sections that overlook the river below. This part feels more scenic, with deeper views into the gorge.

According to the trail information, this route follows the valleys of the Mellte and Hepste rivers, and you can really sense that as you walk along the higher sections.

There are a few junctions along the way, but signposts make it clear which direction to follow.

Final Descent to the Waterfall

This is where the walk changes.

The last section down to Sgwd Yr Eira is steeper and more uneven. The path becomes rocky, with loose stones and some muddy patches. It can also be slippery, especially if it has rained.

You will need to slow down here and watch your footing. Walking shoes are not just a nice idea at this point. They are needed.

But this part also adds to the experience. It feels a bit more rugged and natural. You know you are getting close. And then, quite suddenly, you hear the waterfall properly for the first time.

 

Walking Behind Sgwd Yr Eira Waterfall

This is the highlight of the walk.

As you reach the waterfall, it does not feel massive at first. Then you get closer and realise what makes it special.

There is a clear path that takes you right behind the falling water.

You walk along a rocky ledge, with the cliff on one side and the waterfall pouring down just in front of you. The closer you get, the louder it becomes. You can feel the force of the water and the spray hitting your face.

It is misty, noisy and a bit chaotic in the best way. Once you step behind it, the view completely changes. You are looking out through the curtain of water towards the open space and the people standing in front of the falls. It gives you a very different perspective compared to just standing at the front.

It was a lot of fun. We saw people taking photos, waiting their turn to walk behind, and just standing there taking it all in.

Just take your time here. The ground is uneven, and the rocks can be wet and slippery. Good grip makes a big difference.

 

Is the Sgwd Yr Eira Walk Difficult?

Overall, it is manageable for most people.

The main path is easy. The tricky bit is the final descent and climb back up.

We saw people of all ages. Some had dogs. Some were taking it slow. Others were moving quickly. A few people were setting up drones in open spots.

It is not suitable for pushchairs or anyone who struggles with uneven ground.

Best Time to Visit Sgwd Yr Eira

We visited in April and the waterfall flow was good. The weather was pleasant and, luckily, it was not raining.

Each season will feel different:

• Spring for fresh greenery
• Autumn for colours
• After rain for stronger flow

Just avoid very wet days if you can. The path can get slippery.

What to Wear and Bring

Keep it simple, but be prepared for mixed conditions.

• Proper walking shoes: This is the most important one. The final section near the waterfall is rocky and can be slippery. Trainers might be fine in dry weather, but walking shoes with good grip are a safer choice.
• Waterproof jacket: Even if it is not raining, you will feel the spray when you walk behind the waterfall. A light waterproof helps.
• Water and snacks: It is not a long walk, but you will likely spend more time here than you expect. We stopped a few times along the way.
• Phone or camera: You will want photos, especially behind the waterfall. Just be careful with water spray.
• Small backpack: Makes it easier to carry everything and keeps your hands free on uneven sections.
• Optional: spare socks. Not essential, but useful if you get wet near the falls.

The main thing is to be ready for mud, damp paths and uneven ground, especially on the descent and around the waterfall itself.

Photography Tips

This is a great spot for photos, and you get a few different angles without much effort.

• Start from the front of the waterfall: This gives you the full view. You can capture the height, the flow, and people for scale. It helps show how big it actually is.
• Then walk behind the falls: This is where it gets interesting. You can shoot through the falling water, which gives a very different feel. It is not something you get at most waterfalls.
• Watch for water spray: Your lens will get wet, especially behind the waterfall. Keep wiping it, or your photos will come out blurry.
• Use people in your shots: It adds scale and makes the scene feel more real. We saw quite a few people standing near the falls or walking behind it.
• Go early or later in the day: The light is softer, and there are fewer people. Midday can feel a bit flat and busy.

We also saw a few people flying drones. It shows how popular this spot is, but it can get a bit crowded, so just be mindful of others.

Facilities Nearby

Facilities are quite limited, so it is best to plan ahead.

• Parking at Dinas Rock Car Park: This is where most people start the walk. It is simple but convenient.
• No facilities on the trail: There are no toilets, cafes, or shops once you start walking.
• Nearby options are limited: The closest places are in Pontneddfechan, but even there, choices are not extensive.

It is best to bring what you need with you.

Tips for Visiting

A few simple things can make the walk much better.

• Go early if you can: It gets busy, especially near the waterfall. Early morning is quieter.
• Take your time: The walk is not long, but there is a lot to enjoy along the way. We stopped quite a few times.
• Be careful on the final descent: This is the trickiest part. It is rocky and can be slippery, so slow down here.
• Do not rush the waterfall: Spend some time there. Walk behind it, take photos, and just enjoy it.

We saw people picnicking near the waterfall, others just sitting on rocks, and some taking their time with photos. It is one of those places where it is worth slowing down.

Is Sgwd Yr Eira Worth Visiting?

Yes, it is. And it is easy to see why it is one of the most popular walks in the area.

The walk itself is enjoyable without being too difficult. You get a mix of woodland paths, river views and a bit of uneven terrain towards the end to keep things interesting.

But the real reason to come here is the waterfall.

Being able to walk behind it makes it feel very different from most other waterfall walks. It is not just something you look at from a distance. You actually experience it.

If you enjoy nature, easy to moderate walks and something a bit unique, this is well worth doing.

Combine With Nearby Walks

This area is known as Waterfall Country for a reason. There is a lot more to see beyond just Sgwd Yr Eira.

While on this holiday, we also did the Henrhyd Waterfall trail, which is the tallest waterfall in South Wales. It offers a different experience but is just as worth visiting.

If you have more time, you can link multiple waterfalls together or explore other trails in the area. It is easy to turn this into a full day out.

Staying somewhere nearby, like we did, makes it even easier to explore at a relaxed pace.

This walk ended up being one of the highlights of our stay near the Bannau Brycheiniog National Park.

It is not complicated. It is not overly long. But it delivers exactly what you want from a walk like this.

You get peaceful woodland, changing scenery along the way and then a really memorable finish at the waterfall.

Take your time with it. Stop along the route. And when you reach the waterfall, do not rush. That short walk behind the falls is what makes the whole experience stand out.
