Impressive waterfall. You can also walk well underneath it.

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.

Sgwd yr Eira is the most impressive waterfall in the Pontneddfechan area. It is a high, broad, and powerful waterfall that resembles a curtain of water when it is in full flow. The fact that you can walk behind it just adds to the beauty of this amphitheatre you find yourself in. To get there, however, you have to take around 170 steps that go down the steep side of the valley to the river bed. If this worries you somewhat, just take your time when you go down and when you come back up. In addition, at the bottom, the path that goes to the waterfall is rocky and slippery, and if you walk behind the waterfall, it will be a bit wet, so a waterproof might be necessary.

The Four Waterfalls Walk is my idea of heaven. Hidden away in a quiet corner of the Brecon Beacons, there is a famous waterfall trail that takes in four great waterfalls, it is located near the quaint village of Ystradfellte. The trail has stunning scenery, and the main access to it is from the car park at Porth yr Ogof, or the Cwm Porth car park, to give it its proper name. The Four Waterfalls are all spectacular in their own different ways, and they are Sgwd Clun-Gwyn, Sgwd Isaf Clun-Gwyn, Sgwd y Pannwr, and Sgwd yr Eira.
