<!--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>
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>
