Cribyn is the smallest of the Brecon's 'big Three, but it is a shapely top and should be included in any climb up here.

Great walk that's pretty accessible for most people to achieve, challenging but doable! The route I took incorporated Lord Hereford's Knob. I published it on Komoot here: https://www.komoot.com/tour/1576268965 And on my blog here (with extra commentary for my own entertainment!): https://weekendwalk.co.uk/route/hay-bluff-walk/

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.

For breathtaking panoramic views, Pen y Fan, the highest peak in South Wales, is an excellent choice. On a clear day, you can see across the Bristol Channel, the Gower Peninsula, and the Black Mountains. Its neighbor, Corn Du, also provides stunning vistas down into Llyn Cwm Llwch. For a different perspective, Fan y Bîg offers incredible ridgeline views and its famous 'Diving Board' for unique photo opportunities.
Yes, if you're looking for a quieter experience, consider Fan Fawr. It provides all the stunning views of the Brecon Beacons but with fewer people. Similarly, Cribyn, with its distinctive pyramidal shape, is generally less crowded than Pen y Fan and offers impressive northward vistas. Waun Fach in the Black Mountains is also more remote, perfect for those seeking isolation and expansive moorland views.
Many peaks boast unique features. Pen y Fan and Corn Du both have ancient Bronze Age cairns on their summits. Fan y Bîg is famous for its 'Diving Board' rock formation. In the Black Mountains, Sugar Loaf has a distinctive conical shape, while Fan Brycheiniog overlooks Llyn y Fan Fach, a glacial lake steeped in legend. Table Mountain (Crug Hywel) is topped with an ancient hillfort, and Cefn yr Ystrad features unique limestone pavements.
While many peaks offer challenging routes, some are more accessible. The popular 'Motorway' route to Pen y Fan from Storey Arms is considered an easier ascent suitable for various fitness levels. Sugar Loaf near Abergavenny is also a popular choice for walkers of all levels, with manageable to steep climbs and well-marked trails, making it a good option for families.
For experienced hikers seeking a challenge, the Horseshoe Ridge Walk, which encompasses peaks like Pen y Fan, Corn Du, and Cribyn, offers a demanding multi-peak trek. The ascent to Cribyn, especially from the north-east, is known for its steepness. Fan Fawr also presents a more rugged path and a steeper climb than Pen y Fan, rewarding with equally stunning views.
Beyond hiking, South Wales offers a variety of outdoor activities. You can find excellent hiking trails, including the popular Pen y Fan and Corn Du Circular Walk. For cyclists, there are numerous road cycling routes and general cycling routes, such as the Swansea Ironman route or the Cardiff Bay Trail. The Black Mountain area is also known for stargazing due to its low light pollution.
The mountain peaks in South Wales can be enjoyed year-round, but the best time often depends on your preference. Spring and autumn offer pleasant temperatures and vibrant landscapes, with fewer crowds than peak summer. Summer provides longer daylight hours, ideal for longer treks. Winter can be challenging with colder temperatures and potential snow, but it offers a unique, wild beauty for experienced hikers.
Yes, several peaks have historical significance. The summits of Pen y Fan and Corn Du are marked by ancient Bronze Age cairns. Skirrid Fawr, also known as the Holy Mountain, has the ruins of an Iron Age hill fort and a medieval chapel at its summit. Table Mountain (Crug Hywel) is also topped with an ancient hillfort, offering a glimpse into the region's past.
The Brecon Beacons National Park, where many of these peaks are located, has various towns and villages offering accommodation, pubs, and cafes. Abergavenny is a good base for exploring the Black Mountains, including Sugar Loaf. For specific amenities, it's advisable to check local resources for the particular area you plan to visit.
The Black Mountains, located in the eastern part of the Brecon Beacons, are characterized by their rolling moorland and more remote feel compared to the central Brecon Beacons. Peaks like Waun Fach offer a sense of isolation and expansive views. The area also includes distinctive features like the conical Sugar Loaf and historical sites such as ancient hillforts, providing a unique blend of natural beauty and heritage.
The highest peak in South Wales is Pen y Fan, standing at 886 meters (2,907 feet). Its summit is marked by an ancient Bronze Age cairn, and the mountain itself has a distinctive pyramid shape. It's renowned for offering breathtaking panoramic views that can stretch across a vast area on a clear day, making it a classic South Wales summit experience.
Absolutely! The 'Diving Board' on Fan y Bîg is one of the most photographed locations in the Brecon Beacons, especially at sunrise or sunset. The dramatic escarpment views from Fan Brycheiniog over Llyn y Fan Fach also provide stunning photographic opportunities, particularly with the glacial lake and rugged landscape.
