This is the col between Corn Du and Craig Gwaun Taf. Not only is it a fine viewpoint, but it is also the parting of the ways. Turn right at the marker stone you will follow the crowds down to the Storey Arms, turn left to Craig Gwaun Taf and you arfe likely to have the airy path all to yourself.

This is the ridge route to Pen y Fan from the north. A fine route that steepens sharply near the top.

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

Fantastic views from the top. Just take your time and don’t burn those legs out too soon.

What is the best time of year for mountaineering in this region?

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.

Can I bring my dog on the mountaineering trails?

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.

Are there any less-known or 'hidden gem' routes for experienced mountaineers?

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.

What are the winter mountaineering conditions like around Llanfrynach?

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.

What should I wear and bring for an autumn mountaineering trip?

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.

Where can I find parking for the mountaineering routes?

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.

Are there any cafes or places to eat near the mountaineering routes?

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.

Public transport to the more remote trailheads can be limited. Some bus services operate within the Brecon Beacons National Park, connecting larger towns like Brecon. However, for direct access to many mountaineering starting points, driving or arranging a taxi is often the most practical option. Always check local bus schedules in advance.
