This is considered a difficult hike, requiring good fitness due to significant uphill climbs. While paths are generally well-worn, expect very steep ascents and undulating terrain. Some sections can be boggy, especially after rain.
The full loop is a substantial undertaking. Given its distance of over 32 km and significant elevation gain, it typically takes around 9-10 hours to complete, depending on your pace and breaks.
The route offers spectacular panoramic views and notable landmarks. You'll pass by the historic Crickhowell Castle ruins, the scenic River Usk, and the summit of Crug Hywel (Table Mountain). Key viewpoints include Pen Cerrig-calch summit and Pen Allt-mawr. A major highlight is the ridge to Waun Fach, leading to the Waun Fach summit, the highest peak in the Black Mountains, offering commanding views over the Brecon Beacons and Wye Valley.
The tour starts near Crickhowell, which offers various parking options. It's advisable to check local parking availability and regulations in Crickhowell before your visit, especially during peak season.
Crickhowell is served by local bus routes, which can connect you to larger towns with train stations. Check local bus schedules for services to Crickhowell to plan your journey.
The best time to hike is generally from late spring to early autumn (May to September) when the weather is more stable and the days are longer. Winter conditions can be very challenging, with snow, ice, and strong winds, making the route significantly more difficult and potentially dangerous.
Dogs are generally welcome on this trail, but they must be kept on a leash, especially when passing through farmland or near livestock. This is crucial for the safety of your dog and local wildlife, particularly ground-nesting birds and wild ponies.
No, there are no specific permits or entrance fees required to hike the Cambrian Way and Waun Fach Loop within Bannau Brycheiniog (Brecon Beacons) National Park. However, please respect the National Park's regulations, such as keeping dogs on leads and taking all litter home.
You might spot wild ponies grazing on the moorland. The area is also home to various bird species, including skylarks, golden plovers, and majestic red kites soaring overhead, adding to the sense of wilderness.
Yes, the route incorporates significant sections of the Cambrian Way, which makes up over 50% of the trail. It also crosses parts of the Beacons Way and the distinctive Dragon's Back ridge.
Given the trail's difficulty and varied terrain, proper walking boots are essential. Bring plenty of water, especially as there are limited natural water sources on the higher sections. Layers of clothing, waterproofs, navigation tools, and snacks are also highly recommended.
My time is grabbing spring with both hands and taking on an entire range in a day, solo. My time is going fast and light, on my own terms and at my own pace… An epic day traversing the main spine of the Black Mountains range in the Brecon Beacons National Park. I’d been eyeing up this huge horseshoe route for a while and with new Keen ( @KEEN Footwear ) NXIS hiking sneakers promising a fast and light approach, I thought #thisismytime and went for it. Starting and finishing in Crickhowell, this is a long route, totalling 19 miles and over 1,000 metres of elevation. Comfort on the trail was key and was provided by the NXIS. With my heels held firmly in place and loads of space for my toes, there was no hint of my feet sliding during descents, no bunched up toes and a cosy fit the whole way around. Great returning to a fast and light hiking approach after starting the month winter mountaineering in Scotland. While winter is my favourite, there’s something so liberating about going fast and light, running the downhills and striding purposefully through a big route like this.
