The Taff Trail (Welsh: Taith Taf) is a walking and cycle path that runs for 55 miles (89 km)[1] between Cardiff Bay and Brecon in Wales.
Along much of its length, it follows the National Cycle Network Route 8 (Lôn Las Cymru) that continues to Holyhead, and is substantially off-road.
The project was initiated and co-ordinated by the Merthyr and Cynon Groundwork Trust, with the co-operation of the local councils through whose areas the trail passes.
Taff Ely borough council had created cycling routes within its boundaries, Cardiff city council had provided the Three Castles Cycle Route from Caerphilly into Cardiff, and the Brecon Beacons National Park was developing leisure trails to encourage the use of the park.
The Groundwork Trust for Merthyr Tydfil and Rhondda Cynon Taf saw a need for the co-ordination of these efforts, and the Taff Trail was born.
These routes, which although disused had remained largely intact, proved ideal for the needs of the trail, providing a convenient path along the narrow Taff valley.
In this area (as with most of the path within Cardiff Council boundaries) pedestrians have been given priority, despite the national cycle route status of the trail.
[7] The Castell Coch grounds act as a lay by near the visitor centre, the Fforest fawr car park has been used by cyclists as a base to ascend the hills.
It is very easy to get lost in Merthyr, and travellers may find it easier to ignore the Route 8 signs, and follow their road map instead.
From Merthyr, the trail continues across Cefn Coed Viaduct, through Cefn-coed-y-cymmer, then follows the Taf Fechan (the smaller of the two main tributaries of the River Taff) past Pontsticill Reservoir.
Descending the mountain, cyclists can avoid the slow rough track on the east side of Talybont Reservoir by taking the road along the west bank, on which traffic is normally very sparse.
A second route exists - also called the Taff Trail - from Cefn Coed to Brecon along the Taf Fawr (more or less parallel to the A470 road, but often on the opposite side of the valley) via the Garwnant Visitors Centre.
