This is a great family walk that can be done in half a day and provides great views. A good walk if you’re not comfortable navigating and if you want a relatively straightforward trek. It can boggy throughout with a little bit of testing terrain heading to the summit. Not a walk to do in low visibility or driving rain. Make sure you have good boots, waterproofs, snacks and drinks and a map (OS Landranger 160) and compass. Visibility can drop here so a map is essential and the knowledge to use if is a must.
Also, if you decide to walk Fan Frynych in the Winter, be especially careful on the descent as it is steep and a slip could put you a long way down the mountain.
Park at the lay by opposite Storey Arms on the A470 (Sat Nav LD3 8NL). Follow the path from the lay by West. This vague path heads straight up the slopes, and over several false summit until you reach the spot height (464mtr). At this point the path mingles nicely with the bogs and streams, but if you head due east uphill you will cross the path on the ascent of Fan Frynych. Rocky at times, however there are some obvious mud steps that ascend the face diagonally. As you reach the brow of the ridge, keep an eye out for the path that bears left to the trig point. Walk along the plateau for 10mins to the trig point. If is clear enjoy the views, although you will notice that the trig point doesn’t seem to be on the top – it isn’t. You can either descend back the way you came which would make this entire walk about 2hrs or you can now follow the path SE (not much of a path, but mainly shorter grass) and follow it along the top of the ridge overlooking the Beacon Reservoir. When you are about half way along the length of the reservoir head down to the water and follow its nearest bank, above the tree line, keeping the reservoir to your right.
Follow the vague line that runs parallel to the A470 and follow it back along to the car park.
This is a lovely walk, suitable for all levels of fitness and a little bit of stamina.
