Walk up Cadair Berwyn from Pistyll Rhaeadr Details

Cadair Berwyn at 832 metres is the highest point in the Berwyn Mountains, a vast expanse of high ground and heather to the east of Snowdonia. The Berwyn Mountains don’t have the same status of protection as the Snowdonia National Park, though a token gesture has been made to include the northernmost summits of Moel Fferna and Vivod Mountain into the Clwydian and Dee Valley AONB.

Pistyll Rhaeadr at the start of this walk is often mistakenly quoted as being the tallest waterfall in Wales or even the UK, depending on how you measure it. However, it barely breaks into the top 10 of tallest by height, and is 9th by single cascade (source). Despite the misconception, it can still lay claim to be one of the most spectacular in the country!

The walk up Cadair Berwyn starts off from the Pistyll Rhaeadr car park, which in itself is a challenge to get to by car as there’s no public transport. It initially  skirts Pistyll Rhaeadr before climbing uphill along a good mountain track to the mountain tarn of Llyn Lluncaws. It’s a steep ascent along the top of Craig Y Llyn before the summit of Cadair Berwyn is reached.  Cadair Berwyn’s original summit used to be what’s now called Cadair Berwyn North Top, but it was found to be 3 metres lower than the current summit as recently as the late 1980s, and why the trig point is on that summit. That has now been extended to a whopping 5m higher! You may wish to extend the route to visit that top as well (if you’re hunting Nuttalls, then you probably will!)

Finaly, the route descends over Moel Sych and Trum Felen to finish off near the top of Pistyll Rhaeadr.
