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”.

Description of Route to the reserve
1. Go through the gate by the cattle grid. At the nature reserve interpretation panel go straight ahead for a short distance. At the Merthyr Naturalists sign go right to the edge of the green . Follow this left hand edge looking ahead in case of stray golf balls.
2.Take the path straight on which may be somewhat over grown but improves further on. Avoid following the wider track as this passes under where golfers tee off down the course and they may not see you.
3. Take this path uphill parallel to the electricity pylons about 50m away. The fairways/mown grass should always be on your right, the track veers left a bit.
4. On Reaching a broken down wire fence almost at the top of the golf course look for a track carrying on uphill between two old gate posts. Follow this faint track over open ground for about 500m until on the left you can see the first stile with its post. By this point you are in the nature reserve on both sides of the fence which was erected as a safety feature.
You can cross the stile into the reserve where interesting flowers and ferns thrive with less grazing pressure. For the surefooted with a head for heights it is possible to walk along a way and then exit at stile no. 2 or 3.
It is possible to carry on north following the ridge along sheep tracks and then return over the small summits and cairns of Cefn Cilsanws. This is across open country and should only be attempted with a map compass and weather giving good visibility.
Please return via the out-going route to avoid the golfers.
PLEASE NOTE. This route replaces the old one which has become mostly impassable by summer due to bracken growth. If visiting winter-early summer there are more routes passable.
