It lies on either side of the valley of the Clyne River and comprises an area of over 700 acres (280 ha) of land running from the sea at Blackpill, Swansea, inland to Gowerton.
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.
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.
The aims of the project are: A cycle track crosses the centre of the valley, linking Blackpill on Swansea Bay with the inland village of Gowerton.
The plan is grant-funded through the Forestry Commission's 'Better Woodlands for Wales' scheme, and includes a substantial investment into Mountain Bike facilities in Clyne.
