The River Usk rises on the northern slopes of the Black Mountain (y Mynydd Du), Wales, in the westernmost part of the Brecon Beacons National Park. Initially forming the boundary between Carmarthenshire and Powys, it flows north into Usk Reservoir, then east by Sennybridge to Brecon before turning southeast to flow by Talybont-on-Usk, Crickhowell and Abergavenny after which it takes a more southerly course.

Beyond the eponymous town of Usk it passes the Roman legionary fortress of Caerleon to flow through the heart of the city of Newport and into the Severn estuary at Uskmouth beyond Newport at Newport Wetlands. The river is about 125 km (78 mi) long.

The Monmouthshire and Brecon Canal follows the Usk for most of the length of the canal.

Cwmdu Village

Highlight • Pub

Cwmdu is a lovely little village and a great base for adventures in the Brecon Beacons National Park, with the Central Beacons and the Black Mountains ranges both nearby. The village is home to both a pub, the Farmer's Arms, and the Mynydd Ddu Tea Rooms, as well as a community-run shop. The Beacons Way long-distance footpath passes through the village on its way from Crickhowell to Llangynidr.

Llangynidr Bridge

Highlight • River

Welsh: Coed-yr-Ynys Bridge

Stone bridge, dating from around 1700, would be the oldest bridge over the Usk.
About half a century before the construction of the current stone bridge, there was already a wooden bridge here.

The bridge is so narrow that by means of traffic lights are arranged so that people can cross alternately in one direction.
As a pedestrian you must take shelter in one of the refuge areas on the bridge.
Very beautiful place!

Llangynidr Stone Bridge

Highlight • Bridge

Nestled in the Usk Valley, between the upland massifs of the Central Beacons and the Black Mountains, is the village of Llangynidr. It is superbly situated as a base from which to explore the Brecon Beacons National Park and has a number of good accommodation options. The finest sight in the village is its Grade I-listed stone bridge.

From Llangynidr, a hike up one of the Beacon's few standalone hills, to the summit of Tor y Foel at 1,808 feet (551 m), is recommended. The ascent rewards with excellent views back towards Sugar Loaf and the top is a great vantage for the Central Beacons.
