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.

When coming off the mountain to go down towards the car park it’s quite a steep scramble and can be slippery

The mountaineering routes around Llanfrynach traverse the heart of the Brecon Beacons, offering stunning natural and historical landmarks. You'll encounter prominent peaks like Pen y Fan, Corn Du summit, and Cribyn Summit. You might also pass by viewpoints such as Fan Frynych Trig Point and reservoirs like Lower Neuadd Reservoir.
Spring and autumn generally offer the most pleasant conditions for mountaineering around Llanfrynach, with cooler temperatures and often clearer skies. Summer can be beautiful but also busy, while winter brings challenging conditions requiring appropriate gear and experience due to snow, ice, and rapidly changing weather.
Many trails in the Brecon Beacons National Park are dog-friendly, but it's crucial to keep dogs on a lead, especially near livestock and during ground-nesting bird season (March-July). Always check specific route guidelines and be prepared to clean up after your pet.
While the main peaks are popular, you can find more secluded experiences. For a challenging and less-trafficked option, consider the Corn Du summit – Pen y Fan loop from Beacons Reservoir, which is a difficult 18.9 km route offering extensive views and a comprehensive exploration away from the busiest sections.
Winter mountaineering in the Brecon Beacons, particularly on peaks like Pen y Fan and Corn Du, can be demanding. Expect snow, ice, strong winds, and significantly reduced visibility. Proper winter gear, including ice axe and crampons, and experience in winter navigation are essential for safety.
For autumn mountaineering, layering is key. Wear moisture-wicking base layers, a warm mid-layer (fleece or synthetic insulation), and a waterproof and windproof outer shell. Sturdy hiking boots with good ankle support, a hat, gloves, and a backpack with water, snacks, a map, compass/GPS, and a headlamp are also highly recommended as daylight hours shorten.
Parking is available at several key trailheads. Popular starting points often have dedicated car parks, such as the Neuadd Car Park, which serves routes like the Corn Du summit – Pen y Fan loop from Neuadd Car Park. Beacons Reservoir also offers access to routes like the Pen y Fan Summit loop from Beacons Reservoir. Arrive early during peak season to secure a spot.
While the immediate vicinity of the mountain trails is wild, you'll find cafes and pubs in nearby villages and towns such as Brecon or Libanus. It's advisable to carry sufficient food and drink for your hike, especially for longer routes, and plan your post-hike refreshments for when you return to a populated area.
