Bannau Brycheiniog (Brecon Beacons), Wales
By The Alpines · Updated 2025-07-22 · 8 min read
At 886m, Pen y Fan is the highest peak in southern Britain and the crown of the Bannau Brycheiniog (Brecon Beacons). The most popular route — the well-made path from Pont ar Daf, sometimes nicknamed the "motorway" — climbs steeply but directly to the summit, making it one of the most accessible real mountains in Wales.
The path climbs the broad flank of Corn Du before dipping to a saddle and rising again to the flat, distinctive summit of Pen y Fan. From the top, the view stretches across the rolling Beacons, the Usk valley, and on clear days as far as the Bristol Channel and the coast. The classic "Horseshoe" extension adds Cribyn and the airy ridge for a longer, more rewarding day.
Pen y Fan is famous as a fitness proving ground — it hosts the "Fan Dance", the brutal loaded march used in military selection, and countless people use it to build hill fitness. Short, steep, and satisfying, it is one of the best mountains in Britain for training your legs and lungs for bigger objectives.
From the Pont ar Daf car park on the A470, the path climbs steadily on a well-repaired stone track up the broad shoulder below Corn Du. It is a consistent, honest climb with no scrambling — the gradient is the main challenge. As you gain height the ground opens out onto the ridge saddle at Bwlch Duwynt.
From the saddle you can go over or around Corn Du, then drop to the col and make the final short, steep pull onto the flat summit of Pen y Fan. Soak in the view, then either retrace your steps or, for a bigger day, continue over Cribyn and around the classic Horseshoe. The descent on the main path is quick but steep on tired knees.
Pen y Fan is walkable all year, and its short length makes it a great choice even on shorter winter days — though snow and ice on the steep summit slopes call for care and sometimes microspikes from December to March. Spring and autumn give the best mix of firm paths, quieter trails, and clear views.
The Pont ar Daf car park is very popular and fills early on sunny weekends and holidays. Arrive before 9am, or start from Storey Arms slightly further along the A470. Because the walk is short, it is ideal for a loaded-pack training session — many people carry weight to build fitness for bigger mountains.
A short mountain with a steep, sustained climb — around 500m of ascent packed into a couple of kilometres. There is no technical difficulty, which is exactly why it is such a good, safe place to build leg and lung fitness, especially with a loaded pack.
