Embark on a challenging 15.5-mile (25.0 km) hike through the Bannau Brycheiniog (Brecon Beacons) National Park, tackling the iconic peaks of Pen y Fan, Cribyn, and Fan y Big. This difficult route involves a significant 3658 feet (1115 metres) of elevation gain, with rocky paths and multiple steep climbs and descents, including the famous "Jacob's Ladder." You will experience dramatic panoramic views from the summits, especially from Cribyn, looking out towards Pen y Fan's steep eastern flank and the distant Bristol Channel on clear days.

Tips from the Community
In wet weather the down climb section becomes incredibly hard to stay upright on. Slipped multiple times, a few people even had to do a bum shuffle down for safety. Would recommend reversing the route to go up the muddy side and down the more rocky side.

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.

There’s a lay-by for vehicles just at the start. It’s far enough away from Pen Y Fan to not get busy

Craig Cerrig Gleisiad and Fan Frynych Nature Reserve. Moderate graded walk, which is now way-marked from start to finish. The Trail follows an uneven and increasingly steep narrow path and returns along the same route. The reserve is grazed by cattle, sheep and mountain ponies. Please keep dogs under close control.

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.

Frequently Asked Questions

Can I bring my dog on the trails around Glyn Tarell?
Dogs are generally welcome on the trails in Bannau Brycheiniog, but the area is active farmland with sheep. You must keep your dog on a lead and under close control at all times, especially during lambing season (spring). The open moorland trails are great for dogs, but always be mindful of livestock.
Where can I find waterfall walks near Glyn Tarell?
The region is famous for its waterfalls. While not starting directly in Glyn Tarell, a short drive will take you to the highly-regarded Henrhyd Falls, the tallest in South Wales, or the popular Waterfall Country area, which features numerous cascades accessible via well-trodden paths.
What is the best starting point for hikes to Pen y Fan?
