Pen Cerrig-calch and its neighbour Pen Allt-mawr are popular for the views north across to bigger hills of the Brecon Beacons. A tour of the twin summits makes a great morning or afternoon out from Crickhowell. It's a steepish climb, but once you have gained the height, there is a nice & easy high-level walk across the plateau between the cairns. The peak can also be combined with Crug Mawr and Sugar Loaf, both rising just to the east, for a much longer day out.

From the centre of Crickhowell, head out along Llanbedr Road. About 400m past the last houses, a bridleway cuts north towards The Wern.

Footpaths from The Wern head north to Crug Hywel fort, and the start of the climb up. This is the site of an Iron Age hillfort and you can still see a stone/earth rampart. Beyond the fort, the path heads sharply uphill alongside the Trwyn Ysgwrfa spring.

Printing A Walk

Hi there, I did a trial printout of this walk and it worked just as intended. The printout was absolutely fine. How a page is printed is in part determined by the browser you use. Do make sure you use the latest version of your browser. I used Internet Explorer 10.

Problems On Printing

Hi, I have tried printing a walk off your site. However it prints the background over the text so it is unreadable. I had to cut the words out of your site and paste into word in order to have a readable print. This was the URL I was trying to print http://www.carfreewalks.org/walks/424/pen_cerrig-calch_and_pen_allt-mawr

What do you think?
