Less busy than the two peaks further West and with a similar view, especially looking north, maybe the nicer option for a break.The path from here over the ridge is great.

The highest peak in south wales and still a very easy one to reach with a short walk up the too straight and too perfect path from the parking. The view is well worth it and if you choose an exotic time or less good weather it is even relatively quiet up here. National Trust put a sign on top of th cairn which is the standard selfie spot here now - gives a bit mixed feelings as the cairn is an ancient burial site.

Only sligthly lower tha Pen y Fan and close to the 'bigger brother' these two peaks can ideally be combined. From a distance even a bit easier to recognize due to the pronounces plateau on top.

The Diving Board on Fan y Big is one of the most photographed locations in the Brecon Beacons. The views over towards Cribyn and Pen Y Fan are super good, as are the views down towards the Gap. It is great to come up here on a winter weekday, when it is a bit quieter too. It is also a very popular spot for your sunrise and sunset shots. It is easier than it looks to get here, and it doesn't matter which way you come up; the effort is absolutely well worth it.

The walk to the top of Fan y Bîg. takes in some of the most incredible ridge lines in the Brecon Beacons. It’s a steep start, but then you have around 6km of easy ridge line walking, with simply sensational views all the way. Reaching the top is the icing on the cake, and if you luck out with good conditions, with breathtaking views it’s really a very hard spot to leave. As well as the views, you'll also have the chance to step out onto the diving board, one of the most photogenic spots in the area.

The Brecon Beacons National Park offers several popular peaks. Pen y Fan is the highest in South Wales, known for its expansive views. Corn Du summit, the second-highest, is often climbed alongside Pen y Fan. Fan y Bîg Summit and Diving Board is famous for its unique rock formation and stunning vistas, while Cribyn Summit offers dramatic views and is a key part of the Horseshoe Ridge Walk.
The ascent to Pen y Fan can vary in difficulty. The "Motorway" route from the A470 is more straightforward, suitable for casual walkers. However, more challenging options like the Beacons Circuit or Horseshoe Ridge Walk provide a longer, more immersive experience. While not exceptionally high at 886 meters (2,907 ft), it can be tough, especially on windy days or in wet conditions, so sensible footwear is recommended.
The peaks in the Brecon Beacons boast several distinctive natural features. Pen y Fan has a distinct layered appearance due to red sandstone and an ancient Bronze Age cairn at its summit. Fan y Bîg is famous for its "Diving Board" rock formation, a popular spot for photography. The Fforest Fawr area features the snowplough-shaped Picws Du and the enchanting glacial lake of Llyn-y-Fan Fach.
While many peaks offer challenging routes, some are more accessible. Pen y Fan has routes catering to various abilities, including a more straightforward ascent from the A470. For easier hikes, consider exploring the lower slopes of Fforest Fawr or some of the routes in the Black Mountains, which offer diverse paths. Always check route descriptions for difficulty levels.
The Brecon Beacons peaks can be enjoyed year-round, but conditions vary. Spring and summer offer milder weather and longer daylight hours, making them popular for hiking.
