 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.


Completions log and contact                                                     


The route is generally completed in a West to East direction, but can be completed the opposite way.  If you complete the route in less than 24 hours you will be added to the Completions Log. Contact Paul Colley-Davies email: . 

If you are aware of a sub-24 hour completion by anyone who is not on the list, please put them in touch with Paul.  Send Paul a GPX track, with age and sex to support your record or a schedule and a witness list for summits. Consideration is being given for longer completion lists outside of 24hrs to be published on the South Wales Traverse website and Facebook Group.
