It also forms a part of the boundary of the [[Brecon Beacons National Park]]. The river and its [[waterfall]]s are one of the key attractions of the recently designated [[Fforest Fawr Geopark]].
 
The name is probably a reference to [[Saint David]], patron saint of Wales; 'pyrddin' means 'pure man' in the [[Welsh language]].
 
The streams of Nant y Bryn, Nant y Fedwen and Nant Hir come together to form the Pyrddin which flows south-eastwards for 5km / 3mi to its [[confluence]] with the [[Nedd Fechan]]. <ref>Ordnance Survey Explorer map sheet OL12 'Brecon Beacons National Park: western area'</ref>
 
== Waterfalls ==
The Pyrddin is best known for two [[Waterfall Country (Wales)|spectacular waterfalls]], Sgŵd Gwladus and Sgŵd Einion Gam, the ''lady's fall'' and the ''fall of crooked Einion'' respectively. Sgŵd Gwladus is formed where a band of erosion-resistant gritstone known as the 'Twelve Foot Sandstone' creates a lip over which the river plunges. It is easily accessible by footpath from [[Pontneddfechan]]. A notable feature beside the fall is the erratic block of gritstone which was balanced so that it rocked - at least until Victorian times when it was displaced. The ruins of a small building close to the falls are thought to be those of a corn-mill.
 
Sgŵd Einion Gam which is a further 1/2 mile upstream can only be accessed by crossing and re-crossing the river itself. This fall is caused by the presence of a geological [[fault]] which brings another hard sandstone known as the 'Farewell Rock' up against softer mudstones. <ref>[http://www.breconbeacons.org Brecon Beacons National Park website]</ref> <ref>British Geological Survey 1:50,000 map no. 231 'Merthyr Tydfil' & accompanying memoir</ref>
 
== Habitat protection ==
The steep and wooded gorge of the Pyrddin like that of its neighbours, the [[Nedd Fechan]], [[Afon Mellte]] and [[Afon Hepste]] is home to many rare [[bryophytes]] which enjoy the cool humid conditions which exist here. Accordingly it has been designated as both a[[site of special scientific interest]] and a [[special area of conservation]]. <ref>[http://www.ccw.gov.uk Countryside Council for Wales website]</ref>
