Neuadd Horseshoe Wales
If shape and form were the only measure applied to mountains then Corn Du, Pen y Fan, Cribin and Fan y Big, the four central peaks of the Brecon Beacons, would be classed amongst the grandest in Britain. Their sweeping, elegant lines and stately profiles put many more lofty peaks to shame. The most fulfilling way to tackle these four mountains is to complete a round of the lonely and wild valley on the south side occupied by the Neuadd reservoirs. This southern horseshoe exposes you firstly to the wild and remote heart of the Brecon Beacons, with its lonely corners and great expanses of open hillside set against flashing waters. Then, secondly, on high-sculpted ridges you can set out at a fine pace watching the world pass by below you and reach the four main summits with relative ease. This combination of tranquillity on the approaches and then uplifting walking around the crests is what makes this horseshoe a true classic.
