This walk visits the Coed Taf Fawr and a series reservoirs near Merthyr Tydfil. The visitor centre here is considered the southern gateway to the Brecon Beacons National Park. There are lots of good walking paths and mountain bike trails to try here.
The walk starts from the car park and visitor centre located at the northern end of Llwyn-on Reservoir. From here you can pick up the waymarked Taff Trail andf follow it north along the river to Cantref Reservoir. The walk then continues north to visit the pretty Beacons Reservoir.
You then turn south to return to the forest where you pick up other woodland trails to take you back to the visitor centre.
There's also a number of other waymarked paths in the forest including the Willow Walk all ability trail and a sculpture trail with wonderful wooden carvings.
The waymarked mountain biking trails have different grading levels for varying abilities. All the trails start from the car park.

Coed Taf Fawr - - 738230

One of the ubiquitous signs announcing then entrance to some Forestry Commission Wales woodland. Called Coed Taf Fawr on the maps but Garwnant on the signs.

On the edge of Coed Taf Fawr - - 911579

On the edge of Coed Taf Fawr Felling had just commenced in the distant block of conifers.

Across the moor to Coed Taf Fawr - - 911589

Across the moor to Coed Taf Fawr The vestiges of a track can just about be made out under the tussocky grass. This is an area largely left to the occasional sheep and hill pony though they prefer the drier margins of the road which cuts the moor to the west - often with unfortunate consequences for them with their poor road sense.

Garwnant Fawr - - 911571

Garwnant Fawr. The stream gathers water from the great bowl that is Pant y Wern and delivers it down through the forest (seen in the distance) to the Taf Fawr in Cwm Taf. These water gathering grounds are very boggy and very tussocky and cannot be recommended to any traveller.
