Cwm Clydach National Nature Reserve is a 24.8 hectares (61 acres) area of steeply sloping valley-side on Clydach Gorge, 2 miles (3.2 km) east of Brynmawr, southeast Wales. It is protected for its ancient semi-natural beech woods, designated by the Nature Conservancy Council (now managed by its successor authority Natural Resources Wales).The reserve is a part of the Cwm Clydach site of special scientific interest (SSSI) and of the Cwm Clydach Woodlands/Coedydd Cwm Clydach special area of conservation (SAC).There is good public access to much of the reserve through a network of public footpaths, a section of the national cycleway and by public roads. Interpretive panels at access points to the reserve provide maps of the reserve and information.

The River Clydach is a short, steep and fast-flowing river in Monmouthshire and the county borough of Blaenau Gwent in south Wales. It lies within the Brecon Beacons National Park. It is around 10 kilometres (6 mi) in length. The river rises on the southern slopes of Mynydd Llangatwg (51.8122°N 3.1939°W / 51.8122; -3.1939 (River Clydach, source)) then heads south-east through Clydach Dingle past Brynmawr. It then enters the spectacular Clydach Gorge, dropping about 300 metres (1,000 ft) to Gilwern and its confluence with the River Usk (51.8329°N 3.1007°W / 51.8329; -3.1007 (River Clydach, mouth))."Clydach" is a common name for watercourses in south Wales and is thought to derive from an old Welsh word for "swift" or possibly "stoney", both of which would apply in this case.

Ogof Craig a Ffynnon (Welsh for "Cave [of the] Rock and Spring") is a cave in Wales. The cave is about 7 km in length and is located at the base of a quarried rockface in the Clydach Gorge. Water flowing out of the cave is a resurgence of water draining off Llangatock Mountain above.

The Clydach Gorge (also known as Cwm Clydach) is a steep-sided valley in south-east Wales down which the River Clydach flows to the River Usk. It runs for 5.6 kilometres (3.5 mi) from the vicinity of Brynmawr in Blaenau Gwent eastwards and northeastwards to Gilwern in Monmouthshire. The Gorge was one of the first locations in the region to be industrialised though it still retains its natural environment. It has long been an important transport corridor between Abergavenny and the lowlands of Monmouthshire and the northeastern quarter of the South Wales Coalfield. It is now exploited by the A465 Heads of the Valleys trunk road which runs between Abergavenny and Swansea and which serves the Heads of the Valleys sub-region. The Gorge is included within the Brecon Beacons National Park and is a tourist destination in its own right, with facilities including a picnic site, waymarked footpaths, the National Cycle Network and car parking alongside the River Clydach, easily reached from the Heads of the Valleys Road. It includes Smart's Bridge, a cast iron bridge and the remains of a late 18th-century ironworks which are now a Scheduled Ancient Monument. There are also limeworks.
