Brecon Beacons (Pen y Fan) Horseshoe from Neuadd Reservoir walk
A classic horseshoe walk of the Brecon Beacons (Pen y Fan, Corn Du, Fan y Big) around a glacial valley, with an extension to Waun Rydd
|Length||15.3 km (9.5 mi), with 804m ascent/descent. For alternative start points with longer and tougher walk, and for opportunities to cut out some of the ascent and distance, see below Walk Options.|
|Toughness||6 out of 10, with 4 ½ hours walking time.|
The ridge linking the four table-top peaks traversed on this walk (Corn Du, Pen y Fan, Cribyn, Fan y Big) forms the majestic core of the Central Brecon Beacons and contains the three highest tops in South Wales. As a result, this classic horseshoe walk around a steep sided glacial valley is amongst the best ridge walks in South Britain, featuring some spectacular views in all directions in good weather.
From a remote reservoir north of Merthyr Tydfil you climb steeply to reach the ridge, from where the gradient is mostly fairly gentle over good engineered paths as you follow a sequence of steep escarpments to Corn Du and Pen y Fan. Pen y Fan is the southern-most mountain in Britain and a large glacial grassy mound with steep glacial sides.
Note: Corn Du and Pen y Fan are very popular peaks as they can be easily accessed from car parks on the A470. Expect lots of walkers (experienced and not) on that short stretch, in any weather.
The drama of the ridge walk develops best when approached from the Neuadd Reservoir car park, slowly ascending to the ridge and then up to the tops along it, before gently descending back to the start, but the car park is very remote. Therefore 8 other approaches to the ridge are described, enabling a start from:
These starts inevitably add distance and ascent to the walk, making it a very strenuous walk if also completing the full horseshoe. On the other hand they enable numerous variations of the ridge walk, going up one route, completing some of the ridge walk and/or the extension, and descending a different route. For an overview of the various ascent and descent options check the route map on the SWC website and for all details see pages 8 and 15 of the walk directions pdf respectively.

Neuadd Reservoir car park, map reference SO 036 170, is 9 km north of Merthyr Tydfil, 229 km west north west of Charing Cross, 401m above sea level and in Powys, Wales (as are all other start & finish points). The Neuadd Reservoir access road car park, CF48 2UT, car only, no public transport, is about 3.5 hours (265 km) from London. It's a small car park, busy at weekends. In winter (only) you can continue further along to a car barrier with a few side-of-the-road spots by the barrier at the end, but don't block the farmer's gate. The closest facilities (from the south) are the Old Barn Tea Rooms on the road between Neuadd Reservoir and Talybont, the Red Cow Inn in Pontsticill on the way to/from Merthyr (and Cardiff, the M4), or places in Merthyr itself.
Saturday Walkers’ Club: This walk is doable as a daywalk from London if you have motorised transport.
A couple of options not far from the end of the Horseshoe, but more options at the alternative end points, in Talybont and in Brecon. See page 2 of the pdf.
|Stay||Accommodation is available in Brecon, Merthyr Tydfil & Crickhowell, and in the Llwyn-y-Celyn Youth Hostel.|
