The Cwm Banw Horseshoe loop is a challenging hike that generally takes around 6 to 7 hours to complete. This estimate is for moving time, so allow extra time for breaks, enjoying the views, and navigating the varied terrain.
The terrain is quite varied and demanding. You'll encounter well-worn mountain paths, gravel tracks, and some unmade footpaths. Expect significant steep ascents and descents, especially when tackling the peaks. Some sections, particularly on the ridge behind Cribyn, can be boggy due to exposed and eroded peat. Sturdy boots are essential for this upland walk.
This loop offers breathtaking panoramic views across Southern Wales. Key highlights include the 'horseshoe' formation of Corn Du, Pen y Fan, Cribyn, and Fan y Bîg. You'll pass the Bryn Summit Cairn, Waun Rydd, and the Wellington Bomber R1465 Memorial and Crash Site. Other notable spots are the Cairn Below Waun Rydd Ridge and Carn Pica Cairn. You'll also get views of Talybont Reservoir.
While the specific starting point for this Komoot tour isn't detailed, many routes for the Cwm Banw Horseshoe loop typically start from car parks like Neuadd Car Park or Cwm Gwdi. These are often recommended as quieter alternatives to the busier car parks along the A470 for accessing the Brecon Beacons peaks.
Yes, the Cwm Banw Horseshoe loop is generally dog-friendly. However, as it's within Bannau Brycheiniog National Park, it's crucial to keep dogs on a lead, especially during lambing season (typically March to July) and when livestock are present. This helps protect both your dog and the local wildlife and farm animals.
The best time to hike the Cwm Banw Horseshoe loop is during the warmer, drier months, typically from late spring to early autumn (May to October). In clear weather, the views are spectacular, showcasing vibrant green valleys and rugged mountain forms. Winter hiking is possible but significantly increases the difficulty due to harsh weather, ice, and snow, requiring appropriate gear and experience.
No, there are no specific permits or entrance fees required to hike the Cwm Banw Horseshoe loop itself. Access to Bannau Brycheiniog National Park is generally free. However, some car parks may charge a fee, so it's wise to check in advance.
Yes, when hiking in Bannau Brycheiniog (Brecon Beacons) National Park, it's important to follow the Countryside Code. This includes keeping dogs on leads, especially near livestock, taking all litter home, sticking to marked paths to prevent erosion, and respecting the natural environment and local communities. Wild camping is generally not permitted without landowner permission.
Yes, sections of this route overlap with several other official trails. You'll find parts of the Brinore Tramroad, the Taff Trail, the Usk Valley Walk, and Lôn Las Cymru (South) along the way. It also briefly touches upon the Talybont Forest Mountain Bike Trail and Cycle across the Beacons.
Given the trail's difficulty and exposed nature, essential gear includes sturdy, waterproof hiking boots, appropriate layers of clothing for varying weather conditions (even in summer), waterproof outer shells, a map and compass (or reliable GPS device), sufficient water and snacks, and a first-aid kit. Trekking poles can also be very helpful on the steep ascents and descents.
Yes, while Pen y Fan can be very busy, especially from car parks along the A470, you can often find quieter initial sections by starting your hike from areas like Neuadd Car Park or Cwm Gwdi. These routes still lead to the main horseshoe but offer a more serene experience at the outset, particularly during peak times.
