Clydach Gorge, Steep-sided valley in Monmouthshire, Wales.
The River Clydach flows through this 5.6-kilometer gorge, creating a natural corridor between Brynmawr and Gilwern with dense woodland coverage and limestone formations.
The gorge housed multiple ironworks during the Industrial Revolution, with the Clydach Ironworks employing over 1,350 workers by 1841 for iron ore extraction.
The beech woodlands within Cwm Clydach National Nature Reserve span 61 acres and contain ancient trees connected to local Welsh folklore.
Visitors can access three marked walking trails starting from the Clydach Ironworks site, where free parking facilities are provided near the River Clydach.
Smart's Bridge, a cast iron structure, crosses the gorge alongside remains of 18th-century limeworks and scheduled ancient monuments from the Iron Age.
