Heading South towards Merthyr Tydfil from Brecon along the A470, take the left turn that runs down Upper High Street, the old road into Merthyr Tydfil. At a cross roads just before you pass over the Heads of the Valleys Road (A465) turn left up Vaynor Road signposted towards Pontsticill, and after 100m turn left again up Cloth Hall Lane. Take care, this is a narrow and steep lane. Follow it all the way up to its end, passing over a cattle grid and in to the car park of Merthyr Tydfil Golf Club. Park here. Near the entrance to the car park is the reserve information panel and a signposted footpath heading up the hill. On foot, take this path for just over three quarters of a mile up the hill, following a fence line on your left and way marked by BWT posts and arrows. The reserve starts at the point where the fence line becomes new and has a stile in it. The reserve is then in front of you on both sides of this new fence.

Factsheets and Guides for Your Visit
Darren Fawr is the largest and most spectacular of the Trust’s reserves. It consists of a steep hill-side, covered with loose, grey limestone scree, cliffs and an undulating hill-top with good views of the surrounding landscape.
What to look out for
The scree slope is home to the rigid buckler fern. This is one of only two Welsh sites at which it has been found.
Above the scree slopes are the imposing cliffs of Darren Fawr and Darren Fach. Clinging to the rock face of Darren Fach is the rarest tree species in Britain – Ley’s Whitebeam; named after Reverend Augustin Ley who discovered it at this site in 1896. It has a total wild population of about 15 individuals, most of which are at Darren Fach.
The limestone pavements on the reserve are long, low, flattened pieces of rock whose tops are only a few feet above ground level. The limestone has been broken down into blocks by the weather – producing gaps in the limestone, resembling a “pavement”.
