Journey fact:

Merthyr Tydfil was the birthplace to the world's first steam locomotive to carry a paying passenger. The locomotive, known as the Penydarren, was built by engineer Richard Trevithick in 1804. On February 21, 1804, the Penydarren made history by pulling a train of six wagons and 70 passengers along a nine-mile track from Merthyr Tydfil to Abercynon in just over four hours.

Journey Overview

There are few routes to pass through such a collection of stellar scenic locations and towns as the T4, which makes its way through Pontypridd, Merthyr Tydfil, Brecon Beacons National Park, and several charming towns and villages. The landscape is diverse, ranging from rolling hills and lush valleys to rugged mountains and deep gorges, as well as the industrial landscapes of Pontypridd and Merthyr Tydfil and of course the cultural hotspot of Cardiff.

As the bus leaves Cardiff, city life and suburbs gives way to rolling green hills and open countryside. The bus winds its way through quaint villages and small towns, with traditional Welsh stone houses and narrow lanes. As it approaches Pontypridd, customers can see the distinctive arches of the historic railway bridge that spans the River Taff.

The journey continues through the Merthyr Valley, where the hills rise steeply on either side of the road. The scenery here is dramatic, with craggy peaks and rocky outcrops, and the road twists and turns as it follows the course of the river. The forests and hillsides are covered in a patchwork of greens, browns, and golds, with the occasional splash of bright red or orange from the leaves of a lone tree.

As the bus climbs higher, it enters the world famous Brecon Beacons National Park. The mountains rise majestically in the distance, no more atmospheric than when their peaks are shrouded in mist and clouds. The road snakes through narrow valleys and over high passes, with glorious views at every turn. The landscape here is quite wild and rugged. The rolling hills give way to deep valleys, where streams and rivers flow, cutting through the landscape.

This is a gripping journey and the small towns and villages along the way are full of character and charm. Talgarth, with its quaint shops and cafes, is nestled in the heart of the Black Mountains. Builth Wells is a bustling market town, surrounded by lush green fields and gentle hills.

As the bus reaches the end of its journey in Newtown, the scenery changes again, with the rugged peaks and valleys giving way to gently rolling hills and open fields and then more a more urban, but still very captivating, feel as the town approaches to bring the curtain down on one of the most absorbing trips!

A Fab Day Out!

Starting in Cardiff, there are plenty of things to see and do before even getting on-board the bus! The city is a cultural melting pot, it oozes vitality and character and is home to several world-class museums and galleries, including the National Museum Cardiff, which houses an impressive collection of art and natural history exhibits. The city’s historic landmarks, such as Cardiff Castle and the Principality Stadium, are also worth a visit.

As the bus leaves Cardiff behind, the first recommended stop-off is Pontypridd, a small town with a rich industrial heritage. The town’s history is brought to life at Pontypridd Museum, and there are several splendid parks and gardens to explore, including the Ynysangharad War Memorial Park and Taff Vale Park.

Back on board and Merthyr Tydfil beckons, once the iron capital of the world. The town’s Ironworks Museum regales the story of this industrial heritage, while nearby Cyfarthfa Castle Museum and Art Gallery offer a glimpse into the town’s history and culture.

The journey then takes folk through the Brecon Beacons National Park, one of the most beautiful and diverse landscapes in the UK. There are copious attractions to explore here, from the mountain peaks and deep valleys to the tranquil lakes and streams. Some of the most popular sights include the Pen y Fan and Corn Du mountains, the waterfalls at Ystradfellte, and the Brecon Mountain Railway.

As the bus reaches Newtown, one of the town’s main attractions is the Robert Owen Museum, which celebrates the life and legacy of the town’s most famous son. Robert Owen was a social reformer who lived in Newtown in the 18th and 19th centuries, and the museum houses a collection of artifacts, documents, and exhibits that tell the story of his life and work.

Another popular attraction in Newtown is the Oriel Davies Gallery, which showcases contemporary art and hosts regular exhibitions, workshops, and events. The gallery is housed in a beautiful modern building and is a ‘must-visit’ for art lovers.

For those interested in the town’s history, a visit to the St. Mary’s Church is also a ‘must’. The church dates back to the 13th century and is known for its impressive stained glass windows, intricate carvings, and stunning architecture.

Nature lovers will enjoy a visit to the Hafren Forest, which is located just a few miles outside of town. The forest is home to a variety of wildlife, including red kites and otters, and offers a range of walking and hiking trails for all abilities.

Finally, Newtown also has a vibrant shopping scene, with a range of independent boutiques, craft shops, and markets selling everything from handmade pottery and jewellery to locally sourced produce and artisanal cheeses.

Other stops along the route include the charming towns and villages of Talgarth, Builth Wells, and Llanbister, where traditional Welsh pubs, local markets, and stunning countryside views can be enjoyed. There are also several outdoor activities to enjoy, such as hiking, biking, and fishing.
