The Taff Trail runs for 55 miles between Cardiff and Brecon along a mixture of riverside paths, railway paths and forest roads. This section, which starts just north of Merthyr Tydfil and runs to Pontsticill Reservoir in the Brecon Beacons, leaves behind the densely populated areas to the south and heads into the hills.
Merthyr Tydfil is home to Cyfartha Park, with beautiful grounds, a 19th-century castle, Cyfartha Castle Museum and Art Gallery, a miniature railway, play areas and a range of events and activities.
The route crosses the spectacular Cefn Coed Viaduct and passes through woodlands as it climbs gently up to the reservoir at Pontsticill. There are stunning views of the highest mountains in the Brecon Beacons National Park. While the route is mostly traffic-free following a disused railway line, the final section to the reservoir is on quiet roads.
