The South Wales Traverse                                   South Wales

Originally known as the Brecon Beacons Traverse, this 24-hour challenge involves covering 72 miles and ascending some 17000 feet.  It was launched in 1984 having been completed by Derek Fisher and Andy Lewsley the year before in 21-24.
It traverses 31 summits in the Carmathen Fan, Fforest Fawr, Brecon Beacons and Black Mountains areas and may be completed in either direction.  The mountains selected are from the 2000 foot summit tables compiled by George Bridge in his book - The Mountains of England and Wales, 1973.  A dedicated website was launched in 2020 to provide a comprehensive guide to the route - see link below.



The object is to visit the 31 twothousand foot summits listed above. 'The start in the West of the SWT is the eastern side of the road where the A4069  meets the car park at Pen Rhiw-wen at GR SN730184. The finish in the East is the wall  that divides the parking areas to the south of the Priory at GR SO 289278.  Use Explorer maps (1:25000)  EX012 Brecon Beacons: West and Centre and EX013 Brecon Beacons: East.


A selection of schedules is included on the SWT website - see link below.
