Craig Cerrig Gleisiad and Fan Frynych National Nature Reserve

The Craig Cerrig-gleisiad and Fan Frynych National Nature Reserve is centred around a majestic, steep-sided glacial cwm. Both of around equal height at around 2,064 feet (629 m), the summits of Craig Cerrig gleisiad and Fan Frynych watch over the cwm and provide superb views towards Pen y Fan and its siblings.

Though these summits are arguably bettered by the cwm below which, thanks to its steep, salmon-coloured crags, is a haven for rare plant life like roseroot and purple saxifrage. The cliffs are also home to nesting peregrines, while ring ouzels and ravens can often be spotted in the sky too.

A walk up Craig Cerrig Gleisiad can be done from the car park at the base of the Cwm, which is a very steep trail if you come up the direct route. My favourite is to come over from Storey Arms, which is a longer but far gentler alternative with super views across to the central range. Either way, you will end up on this steep, craggy edge of a glorious amphitheatre-shaped valley that is directly below you. Spectacular scenery awaits you and the chance of seeing rare plants and birds.

Moderate trail with some elevation for everyone to enjoy
