The waterfall in the Brecon Beacons you can walk right behind, where a ledge in the rock lets the path run behind the falling water
Sgwd yr Eira, which means the fall of snow in Welsh, is the one people come to Waterfall Country for. The Afon Hepste drops over a broad lip of hard rock, and a ledge runs along the base behind the curtain of water, so you can walk right behind the fall and look out through it. Shepherds once used the same ledge to move sheep across.
It sits in the wooded gorges near Ystradfellte in Bannau Brycheiniog, the Brecon Beacons, and it is the last and best-known stop on the Four Falls trail. That walk also takes in Sgwd Clun-Gwyn, Sgwd Isaf Clun-Gwyn and Sgwd y Pannwr along the way. The drop down to Sgwd yr Eira is on steep steps that get slick and muddy, so proper footwear matters and you will want to take the descent carefully in wet weather.
If you are making a loop of it, Porth yr Ogof, a big river cave mouth where the Afon Mellte disappears underground, is close by and easy to add on.
