Part 1: Cardiff & The Valleys

Power, Industry & the Gateway North

The Cambrian Way begins in Cardiff, a city whose growth and confidence were built on coal, trade, and global ambition. Castles, civic buildings, and docks all tell the story of a capital shaped by industry and empire — and it is from here that the route turns inland, following the valleys that once powered the modern world.

Almost immediately, the landscape tightens and rises. The road leads past Caerphilly Castle, one of the greatest medieval fortresses in Europe, before climbing into the heads of the South Wales valleys. This is a country of steep-sided hills, terraced towns, and extraordinary engineering — where railways, canals, and roads were carved into the landscape to serve mines and ironworks.

Places like Merthyr Tydfil are not just stops on the route, but chapters in the story of how Wales was transformed by the Industrial Revolution. This opening section is about scale and contrast: from capital city to upland edge, from medieval power to industrial might — and about crossing the threshold into the wilder heart of the country.

  • St Fagans was established in 1948 as part of the National Museum of Wales, with the aim of preserving important historic buildings that were at risk of being lost. Rather than keeping them as isolated exhibits, the museum chose to rebuild them in a living landscape, where their original context and interiors could be understood.

    Over time, the collection has grown to include buildings from across Wales, ranging from medieval to modern, creating a unique and evolving record of Welsh life, culture, and identity.

Caerphilly Castle

Caerphilly Castle is the largest castle in Wales and one of the biggest medieval fortresses in Europe. Famous for its vast water defences and dramatic scale, it dominates the town of Caerphilly and is one of the most impressive examples of medieval military architecture in Britain.

Built in the late 13th century, the castle was designed as a statement of power as much as a fortress, using lakes, moats, and massive walls to create an almost impregnable stronghold. Today it is managed by Cadw and is one of the must-see historic sites in south Wales.

How to Visit Caerphilly Castle

Caerphilly Castle sits in the centre of the town of Caerphilly, just north of Cardiff, and is very easy to reach.

  • It is a short walk from Caerphilly town centre and railway station.

  • The castle is visible from many parts of the town and forms the focal point of the area.

Because of its size, allow at least 1.5–2 hours for a proper visit.

    • Explore the vast inner and outer wards – The sheer scale of the castle is immediately striking, with huge open spaces, multiple walls, and extensive defences.

    • Walk the battlements and towers – Several sections are accessible and give excellent views over the town and surrounding countryside.

    • See the Great Hall – Once the ceremonial heart of the castle.

    • Explore the gatehouses and defensive works – Caerphilly is a masterclass in medieval military design.

    • Discover the water defences – The surrounding lakes and moats are a key part of what makes this castle so unique.

    • Find the famous leaning tower – Often compared to Pisa, this is one of the most photographed features of the castle.

    • The leaning south-east tower – A dramatic reminder of the damage caused during medieval warfare.

    • The huge water defences – One of the finest and most complete water-based defensive systems in Europe.

    • The concentric design – Multiple rings of walls showing cutting-edge 13th-century castle design.

    • Gatehouse details and murder holes – Classic features of a castle built for serious warfare.

    • Long sightlines across the lakes – Showing how the landscape itself was used as part of the defence.

  • Caerphilly Castle was built between 1268 and 1271 by Gilbert de Clare, one of the most powerful Norman lords in Wales, during a period of intense conflict with the Welsh prince Llywelyn ap Gruffudd.

    The castle was designed not only to defend territory but also to demonstrate Norman dominance over south Wales. Its innovative use of water defences and concentric walls made it one of the most advanced fortresses of its time.

    Over the centuries, the castle changed hands several times and was involved in various conflicts, including the English Civil War. Although it later fell into ruin, its immense structure survived largely intact, and major restoration work in the 19th and 20th centuries stabilised and preserved it for future generations.

  • Almost as soon as it was built, Caerphilly Castle was attacked and damaged during Welsh uprisings and later conflicts. One of the most dramatic episodes occurred during the early 14th century and again during the English Civil War, when the castle was deliberately damaged to prevent it being used as a stronghold.

    It was during these events that the south-east tower was partially undermined and collapsed, creating the famous leaning tower that still stands today — a powerful visual reminder of medieval and early modern warfare.

  • Getting there:

    • Caerphilly is just north of Cardiff and is easily reached by road or train.

    • Caerphilly railway station is only a short walk from the castle.

    Parking:

    • There are several public car parks in Caerphilly town centre within easy walking distance of the castle.

    Access:

    • The site is large, with uneven surfaces, steps, and towers.

    • Sensible footwear is recommended.

Taff Trail

From City to Countryside

The The Taff Trail begins in Cardiff Bay, passing through the heart of the city via Bute Park and alongside Cardiff Castle, before heading north into the Taff Valley. This gradual transition from urban landmarks to green corridors is one of the trail’s defining features.

Rivers, Woodlands & Valleys

Much of the route follows riverside paths, woodland tracks, and quiet lanes, offering frequent views of the River Taff and the surrounding hills. As the trail climbs northwards, the scenery becomes increasingly rural, with wide views across valleys and uplands.

Historic Landmarks

The Taff Trail passes several notable historic sites, including Castell Coch, the striking 19th-century “fairytale” castle hidden in woodland above the valley, and remnants of Wales’s industrial heritage such as the Taff’s Well Ironworks. These sites reflect the long history of settlement, industry, and transport along the Taff corridor.

Walking & Cycling

The trail is well signposted and largely traffic-free, making it suitable for both walkers and cyclists. Some sections are gentle and ideal for families or short outings, while others offer longer, more challenging stretches, particularly for cyclists heading north towards the Brecon Beacons.

Practical Information – Access & Using the Trail

Access points:
The Taff Trail can be joined at many points along its length, including Cardiff Bay, Cardiff city centre, Merthyr Tydfil, and Brecon. This makes it easy to explore short sections rather than the full route.

Route character:

  • Mostly traffic-free paths and tracks

  • Suitable for walking and cycling

  • Surface quality varies, particularly outside urban areas

Using the trail:
The trail works well for day walks, family cycling, or longer multi-day journeys, depending on how much of the route you choose to explore.

Check out the trail around Cardiff Bay, Merthyr Tydfil and Brecon, among many points to pick it up.

About The Valleys

The Welsh Valleys have a rich and powerful industrial heritage that dates back to the 18th and 19th centuries. Once the heartland of the coal mining and iron industries, the valleys were among the most important industrial regions in the world, with coal mines, ironworks, and factories driving the Industrial Revolution.

This industry shaped not only the landscape but also the communities, culture, and identity of south Wales. Although the decline of heavy industry brought major economic and social change, the Valleys today combine a remarkable industrial story with beautiful natural landscapes, outdoor activities, and a strong sense of place.

Industrial Heritage & Mining History

One of the best ways to understand the Valleys is by visiting the surviving industrial sites and museums.

  • Big Pit National Coal Museum (Blaenavon) – A UNESCO World Heritage Site and one of the most important industrial museums in Britain. Here you can descend into a real coal mine and experience what life was like for Welsh miners. Visiting the Big Pit is one of the most powerful and immersive ways to understand the region’s past.

  • Rhondda Heritage Park – Home to the Welsh Mining Experience at the former Lewis Merthyr Colliery. The Black Gold Experience includes guided underground tours and interactive displays that recreate the world of the Welsh miner and explain how coal powered the Industrial Revolution.

Landscapes, Waterfalls & Outdoor Scenery

The Welsh Valleys are not only about industry — they are also home to beautiful and surprisingly wild landscapes, with rolling hills, wooded valleys, rivers, and waterfalls.

One of the best places to explore is:

Notable waterfalls include:

These lie on the fringes of the Brecon Beacons National Park and are among the most beautiful waterfall landscapes in southern Wales.

Dark Sky Sites & Stargazing

The borough of Rhondda Cynon Taf has no fewer than eight Dark Sky Sites, making this one of the best places in south Wales for stargazing.

Uniquely, two of these sites are pubs:

  • Red Lion – A 12th-century drover’s inn

  • Rose and Crown, Eglwysilan – Situated above Pontypridd and offering panoramic views across the valley

Both allow you to combine stargazing with a drink in atmospheric surroundings.

Merthyr Tydfil

Copyright: Cyfarthfa Museum & Art Gallery

Merthyr Tydfil, located in the historic county of Glamorgan, is one of the most important towns in the story of the Industrial Revolution in Wales. During the 18th and 19th centuries it became a global centre for iron production and coal mining, earning the nickname “the Iron Capital of the World.”

Its rapid rise was driven by abundant natural resources — especially iron ore and coal — and its strategic position along the River Taff. Ironworks such as Cyfarthfa Ironworks and Dowlais Ironworks became among the largest and most productive in the world, driving major technological advances in iron and steel production.

This explosive growth brought huge social change. Workers arrived from across Wales and beyond, leading to overcrowding, harsh living conditions, and growing labour unrest. One of the most dramatic moments was the Merthyr Rising of 1831, when ironworkers rebelled against low wages and oppressive conditions — a key moment in the wider struggle for workers’ rights in Britain.

In the 20th century, heavy industry declined, but today Merthyr Tydfil has reinvented itself as a centre for heritage, culture, and outdoor adventure, combining powerful industrial history with easy access to some of the best landscapes in south Wales.

What to See & Do in Merthyr Tydfil

    • A replica of the world’s first steam locomotive

    • Displays on Laura Ashley and Julien MacDonald, both of whom have strong connections to Merthyr Tydfil

  • Joseph Parry’s Cottage – The birthplace of one of Wales’s most famous composers. This well-preserved 19th-century ironworker’s cottage offers a fascinating glimpse into everyday life during the industrial era and celebrates Parry’s musical legacy.

  • Redhouse – An arts and creative centre in the Old Town Hall, a magnificent Grade II listed building. Hosts exhibitions, performances, workshops, and community events.

  • Ynysfach Engine House – Built in 1836. Currently closed, but worth keeping an eye on. You can read more about the four-storey blast engine house here and check the website for reopening updates.
