Glyn Neath is situated in the county of Neath Port Talbot in South Wales. Set in the valley of the River Neath some 10 miles north of Neath, the town is close to the Brecon Beacons National Park and the river Neath travels through on its way to the estuary below Briton Ferry.
Glyn Neath sits at the entrance to "Waterfall Country", an area of South Wales famous for a series of dramatic waterfalls that are popular with walkers and the ever-growing followers of the extreme sports of canyoning and gorge walking. The rivers Mellte, Nedd, and Pyrddin all combine to form a beautiful landscape at the south of the Brecon Beacons National Park.
Relatives of Oliver Cromwell used to live in Glyn Neath at a large mansion named Aberpergwm House. Bought in 1560 by the Williams family of Blaen Baglan, the house was remodelled in 1876 by Morgan Stuart Williams, who later restored St Donats castle. During the Second World War, the house was used as a school for children evacuated from Gorleston-on-Sea, East Anglia. Soon after the house suffered from a terrible fire and it was never recovered. The ruins now share the site with St Cadoc's Church.
The World Rally Championships is held annually at Glyn Neath and is one of the toughest rounds, for its unpredictable weather conditions.
The town also has a successful rugby union team, Glyn Neath RFC, which was founded in 1889. The team have won several seasons in the Division Three South West of the WRU National Leagues.
