Blaengwrach is a village near Glynneath and Resolven in the county borough of Neath Port Talbot, Wales. It is also the name of a community and an electoral ward of Neath Port Talbot county borough. There are, however, some differences between the boundaries of the community and the ward. The ward had a population of 1,985 in the 2001 census, but 837 of these were actually residents of the neighbouring community of Glynneath and so the population of the Blaengwrach community itself would have been 1,148.The ward population at the census 2011 was practically unchanged.
Blaengwrach is a predominantly upland area, and contains the highest points of three local hills or mountains, namely Mynydd Resolfen (383mt/1257 ft) and the rather more impressive Mynydd Pen-y-Cae (573mt/1880 ft) and Craig-y-Llyn (600mt/1970 ft), both of which offer spectacular views of the valley below and the Brecon Beacons in the distance. Craig-y-Llyn is the highest point in the old county of Glamorgan, and is home to a nature reserve containing Llyn Fach and a Site of Special Scientific Interest. West of the summit is Foel Chwern Round cairn.
The village of Blaengwrach is often confused with the settlement of Cwmgwrach. Traditionally, the two are settlements separated by a stream or brook running through the middle of them. However, the sign welcoming you to Cwmgwrach is actually in Blaengwrach, and in similar fashion, Blaengwrach school is actually in Cwmgwrach, although this could be explained by its being named after the wider ward. In reality the residents call the entire village Cwmgwrach, with Blaengwrach being best used as the name for the wider area in which the village is situated. A history of the village (Cwmgwrach: Valley of the Witch) was written by Ian Currie.
In May 2013, North Bank Entertainment announced that it would soon commence filming of a film called 'Valley of the Witch' which will be an 18 rated horror film based on a true story about events in Cwmgwrach. Filming is due to take place before the end of 2013 on location in Cwmgwrach.
The village itself contains various local shops, pubs and a rugby union club, Cwmgwrach RFC. However, for wider services the village is largely dependent upon Glynneath.
The Neath and Tennant Canal has been restored and now has over four miles of walkable towpath between Resolven and Glynneath. The Vale of Neath Railway is still used for freight transport between Neath and Cwmgwrach.
