The Clyne Valley Country Park is an area of parkland in Britain, at Swansea in south Wales. It lies on either side of the valley of the Clyne River and comprises an area of over 700 acres of land running from the sea at Blackpill, Swansea, inland to Gowerton. It is an area of once splendid woodland with enormous beech, ash and oak trees mainly on the Mumbles side of the Clyne River, and, on the Swansea side, woods and mainly scrub land that has naturally regenerated a reclaimed refuse tip. The valley forms an important link in the ecological corridor that runs from the Brecon Beacons and the Black Mountain across commons and on into the Gower AONB. The Area of Outstanding Natural Beauty forms part of the valley's boundary along Clyne Common. Now dormant – apart from the rich habitat that has formed from neglect – the valley at one time was part of the Vivian estate. During the eighteenth and nineteenth centuries it was a highly active industrial area with a long history of coal mining, mineral workings, brick making, charcoal burning, railways and canals.
