A 65-hectare park above Merthyr Tydfil, railway traces from the 19th century and a wooded limestone gorge offer different directions for your explorations. The region’s history comes to life in homes, collections and tunnels; outdoors, paths, woodland and water shape the scenery. This lets you explore Merthyr Tydfil through the themes that interest you most.
Cyfarthfa: Park, Home and Collection
Cyfarthfa Park extends across 65 hectares above Merthyr Tydfil and is registered as a Grade II* park. Cyfarthfa Castle is a Grade I listed castellated mansion, built in 1824 for ironmaster William Crawshay II. The castle houses a museum and art gallery featuring art, social history and unusual objects—including the world’s first steam whistle. The collections thus bring together varied insights into art and everyday history with an unusual piece of technological history.
Railway Lines and Paths Through History
The Brecon Mountain Railway runs along part of the original route of the railway from Brecon to Merthyr, built in 1859. It reaches Torpantau at the summit of the original line, 1,313 feet above sea level. On the return journey, the train stops at Pontsticill station, where you can visit the Lakeside Cafe and walk along the reservoir.
The Trevithick Tunnel also recalls the history of steam locomotives: it was built for the original journey of a steam locomotive and is considered probably the world’s oldest railway tunnel built for self-propelled steam locomotives on rails. The Trevithick Trail starts in the centre of Merthyr Tydfil and links industrial history with river scenery, woodland paths and public art. Its route uses a mix of traffic-free paths, cycle routes and quiet roads.
Gorge, Woodland and Water
Taf Fechan Nature Reserve covers a 2.5-kilometre stretch of wooded limestone gorge carved by the River Taf Fechan. The reserve lies next to the Taff Trail and includes a large part of Cwm Taf Fechan Woodlands, designated as a Site of Special Scientific Interest. The circular walk through Taf Fechan Gorge leads to the Blue Pool and passes a waterfall and a clear pool. Here, the focus is on the shaped landscape and the path through the gorge.
The Taff Trail runs right in front of the dam at Pontsticill Reservoir. The reservoir was completed in 1927 and built to supply water to communities throughout South Wales. As part of the Reservoir Passport Scheme, visitors can go canoeing, kayaking and stand-up paddleboarding there. Parkwood Outdoors Dolygaer also offers these three watersports. The provider is based in Pontsticill, 15 minutes from Merthyr Tydfil town centre, and also runs climbing, caving expeditions, gorge adventures and team challenges led by qualified instructors.
For mountain bike trails, BikePark Wales offers a different focus. The park is located in Gethin Woodland above Merthyr Tydfil; Kermit is a five-kilometre trail for beginners. Green and blue routes are geared towards beginners and a steady ride, while red and black routes are more technically demanding. The different grades help you choose the type of riding that suits your trip.
Castle Ruins, Stage and Local Food
Morlais Castle was built around 1270 by Gilbert de Clare, Earl of Gloucester and Lord of Glamorgan. Visitors can explore the remains and the vaulted underground cellar. From the hill, there are views across the Taf Fechan Valley and the surrounding landscape. This makes the site interesting both for its medieval history and its views.
In the centre of Merthyr Tydfil, Theatr Soar is located in Pontmorlais. The venue brings amateur and professional artists into contact with audiences; performances, as well as community and professional activities, take place regularly. You can reach the theatre on foot, by bus, by train or by car. At Joseph Parry’s Cottage, a preserved 19th-century ironworker’s home at Number 4 Chapel Row, you can explore rooms furnished as they were in the 1840s. Merthyr Tydfil town centre offers international cuisines alongside traditional Welsh specialities.
