Taff Trail Tramroad Section

Highlight • Cycleway

This is a section of the Taff Trail NCR8 that is unpaved and muddy. Long may this last as the trail has important industrial archeological history. You can still see the stone seats that held the wooden rails of the old tramway in place. For more on the significance, Google Richard
"Richard Trevithick (13 April 1771 – 22 April 1833) was a British inventor and mining engineer. The son of a mining captain, and born in the mining heartland of Cornwall, Trevithick was immersed in mining and engineering from an early age. He was an early pioneer of steam-powered road and rail transport, and his most significant contributions were the development of the first high-pressure steam engine and the first working railway steam locomotive.[1] The world's first locomotive-hauled railway journey took place on 21 February 1804, when Trevithick's unnamed steam locomotive hauled a train along the tramway of the Penydarren Ironworks, in Merthyr Tydfil, Wales.[2][3]

Turning his interests abroad Trevithick also worked as a mining consultant in Peru and later explored parts of Costa Rica. Throughout his professional career he went through many ups and downs and at one point faced financial ruin, also suffering from the strong rivalry of many mining and steam engineers of the day. During the prime of his career he was a well-known and highly respected figure in mining and engineering, but near the end of his life he fell out of the public eye." - from wikipedia. - en.wikipedia.org/wiki/Richard_Trevithick

BikePark Wales Trail Centre

Highlight • Cafe

This is the central hub of Bike Park Wales, with the ticketing office where you can pick up your day pass (pedal up or uplift), a fantastic café, a bike shop with a workshop and bike hire and a pump track.

Handily, there are a few bike racks and plenty of seating here too, as well as a bike wash so you can take your bike home looking fresh! My go-to are the loaded fries for lunchtime, and they make a pretty mean hot chocolate too.

Pontygwaith Bridge

Highlight • Historical Site

Pontygwaith Bridge spans the River Taff just above Quaker's Yard. It's a Grade II-listed stone bridge and really is exceptionally pretty, particularly in summer with the riverbanks are bursting with colour. This bridge dates back to 1811 although there's been a bridge here for hundreds of years prior as well.

Having climbed up from Talybont on Usk alongside the reservoir to essentially the foot of Pen y Fan, this next section of the Taff Trail is a delight. There's a short section of road, including a fast decent, before turning in to pick up forestry fire roads of hard packed loose stone that lead you to the banks of the next reservoir, Pontsticill, there's a further forestry section, with a draggy climb before you pop out at Pontsticill village, don't miss the sharp left at the Red Cow pub as this take you to the disused railway path. This section in particular is a glorious gradual decent on traffic free cycle way to Merthyr Tydfil, perfect for all the family! If you're not getting to Merthyr Tydfil but instead heading to Abergavenny on the NCR 46, don't join the railway path but instead stay on the road

June 21, 2026, Pontygwaith Bridge

Pontygwaith Bridge is a historic, Grade II-listed stone humpback bridge that spans the River Taff near Edwardsville and Treharris, south of Merthyr Tydfil, Wales. Revered for its striking architecture and its setting within the Pontygwaith Nature Reserve, the bridge stands as a prominent icon of the region's industrial heritage. 1. History and Origins Ancient Crossings: Records indicate a river crossing has existed at this precise location as far back as the 1540s. The Ironworks Connection: A wooden bridge originally stood here to carry worker traffic across the river to a small ironworks established in 1583 by Sussex ironmaster Anthony Morley. The current name, Pontygwaith, literally translates to "Bridge of the Ironworks". The 1811 Stone Build: The wooden structure was replaced in 1811 by the beautiful, durable masonry structure seen today. 2. Architectural Features According to the official Cadw Listed Buildings Report, the bridge is registered as a structure of "exceptional character" due to its distinct construction: The Arch: It features a single stone arch built with a remarkably steep rise of 4.8 metres and a wide 16.8-metre span. Materials: It was meticulously assembled using local Pennant Sandstone rubble and thin, long cut stone voussoirs across the arch ring. Restoration: The main arch was heavily repaired and reconstructed by the Mid Glamorgan County Council in 1993, earning it a prestigious commendation from the Civic Trust for historical preservation. 3. Pop Culture & The Taff Trail Today Today, the bridge serves as a major focal point along the Taff Trail (National Cycle Network Route 8). It is a highly popular stopping point for cyclists and hikers to set up a picnic or take photographs. The bridge also gained television fame when it was used as a filming location for the BBC fantasy series Merlin. It served as the exact backdrop for the "Beauty and the Beast" episode, where a character has a secret picnic with a troll directly beneath the stone archway.
