River Mellte

Waterfall Country (or sometimes Waterfalls Country) (Welsh: Bro'r Sgydau) is a name often given to the upper reaches of the Vale of Neath in South Wales. The tourist area around the head of the valley has an unusually large number of publicly accessible waterfalls. The area is not officially defined but generally includes the group of falls on the Nedd Fechan, Pyrddin, Hepste and Mellte rivers, all of which lie between the villages of Pontneddfechan and Ystradfellte in the Brecon Beacons National Park. Each of these falls lies within or on the boundary of the county of Powys. A few miles further west are Henrhyd Falls on the Nant Llech, a tributary of the Tawe and to the south-west are Melin Court Falls on the Melin Court Brook, a tributary of the River Neath. These, along with Aberdulais Falls on the Dulais, a further tributary of the Neath are also encompassed by the term 'Waterfall/s Country' by some writers. Collectively the falls are one of the more popular natural attractions in South Wales, which has caused problems of erosion in the vicinity of many of the falls. Most occupy locations designated as sites of special scientific interest and as special areas of conservation which aim to protect the biodiversity and geodiversity of these sites. The designations place a duty on the landowners and managers to protect the sites and so various erosion control measures have been put in place in an attempt to counter the worst problems.

Pontneddfechan (Welsh for 'bridge over the Little Neath'; pronounced [pɔntˌniðˈvɔːn]; also known as Pontneathvaughan) is a village in Powys, Wales. It is the southernmost village in the historic county of Brecknockshire, within the Vale of Neath and in the community of Ystradfellte. It stands at the confluence of the rivers Mellte and Nedd Fechan ("Neath Vaughan") and gives access to a series of waterfalls that adorn the upper Neath valley. Dinas Rock is a quarried limestone promontory east of the village, popular with visitors.

The Afon Sychryd is a river in Rhondda Cynon Taf, Wales. Although it is a relatively short river, with a total length of 3 miles (5 km), it is notable for the gorge and two waterfalls through which it flows.

Cefn Rhigos (name meaning '(the) ridge (at) Rhigos') is a hamlet (place) to the west of the village of Rhigos, Wales. Despite being eight miles from the town centre, for postal purposes it comes under Aberdare. It is the most westerly named settlement of the Cynon Valley. The border with The Vale of Neath lies a few hundred yards to the west.

Dinas Rock (Welsh: Craig y Ddinas, "Fortress Rock") is a high promontory of Carboniferous Limestone which rises between the Afon Mellte and its left-bank tributary, the Afon Sychryd on the border between the county of Powys and the county borough of Neath Port Talbot in south Wales. It can be found near the village of Pontneddfechan near Glyn Neath at the head of the Vale of Neath. It derives its name from the presence of Iron Age earthworks on its summit, dinas in Welsh signifying a defensive site or "city".

Cwm-Hwnt is a tiny hamlet to the west of Rhigos and south of Cefn Rhigos in the Cynon Valley, one of the South Wales Valleys. It is the farthest named settlement from the town of Aberdare that for postal reasons comes under that town. The name of Cwm-Hwnt comes from the English meaning "Valley Beyond" There was previously a through road to the geographically neighbouring villages of Cwmgwraech and Blaengwraech in The Vale of Neath which was referred to as "the Parish Road". However this road was closed in the late '90s due to the Sellar Opencast mine being dug, and the only routes to these villages are now via Cefn Rhigos and the main roads through Glyn Neath

Rhigos () is a small village on the saddle of higher ground between the Vale of Neath and the Cynon Valley. It was part of the old Neath Rural district Council under Glamorgan until 1974. The village then came under the jurisdiction of The Cynon Valley Borough which subsequently became Rhondda Cynon Taf, South Wales in 1996. It lies just off the old Aberdare road that was the main link between Aberdare and Glynneath, before the A465 road was extended in the 1960s. The hamlets of Cefn Rhigos and Cwm-Hwnt lie to the west of the main village. The population of the community in the 2011 census was noted as 894. For postal purposes it comes under the town of Aberdare, although it is some 7 miles (11 km) from Aberdare town centre, and 2 miles (3.2 km) from Glynneath. It was noted as a township in the parish of Ystradyfodwg in several historical references and people moved to this rural area to work in local industries. Today, the village is a quiet place to live with views of the Brecon Beacons National Park to the north and is within walking distance of Waterfall Country.

The Afon Pyrddin is a river forming a short section of the boundary between Powys and Neath Port Talbot in Wales, United Kingdom. It also forms a part of the boundary of the Brecon Beacons National Park. The river and its waterfalls are one of the key attractions of the Fforest Fawr Geopark designated in 2005. The name could mean 'river by the striking fortress' or 'sweet-flowing river'. The streams of Nant y Bryn, Nant y Fedwen and Nant Hir come together to form the Pyrddin which flows south-eastwards for 3 miles (5 km) to its confluence with the Nedd Fechan (sometimes also known historically in an Englished form "Neath Vaughan"; at one time this would have been a fair indication of the Welsh pronunciation in English spelling, but with changes in English pronunciation it has now diverged considerably)).

British Rhondda Halt railway station served the area of Pont Walby, in the historical county of Glamorganshire, Wales, from 1906 to 1911 on the Vale of Neath Railway.

Foel Chwern is a Round cairn on the edge of the high plateau east of the Neath valley, and near the summit of Craig y Llyn. The headwaters of the River Rhondda are to the south-west. It is a burial monument dating to the Bronze Age, and is sited on the edge of a steep scarp slope, with a wide field of view to the north. The long distance footpath Coed Morgannwg Way runs close by the cairn. Conifer plantations of the Rheola Forest surround the site.
