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.

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.

When you go in search of the trig point it's just off the Sarn Helen in amongst a small group of trees. Look carefully and you e will see a path leading to it.

Hirfynydd is a hill in Neath Port Talbot county, South Wales. A UK-listed Marilyn, it stands at 1,579 feet (481 m). Sarn Helen, a Roman road, runs along its entire northeast–southwest ridge. The ancient route is now a byway. To its west is Cwm Dulais and to its southeast is the Vale of Neath. The northern end of the ridge falls away to a broad upland vale containing the Afon Pyrddin and the Brecon Beacons beyond.

These two red singletrack descents are part of the larger Penhydd trail from Afan Forest Centre. First up, Sidewinder takes you through the woodland on a rocky, narrow trail with a few loose corners. Then you're straight into Dead Sheep Gulley, a more open trail that cuts across the moorland landscape with a bit more pedalling than the last section.
