Torpantau Tunnel is a closed-down, 666-yard-long abandoned masonry railway tunnel in Wales that was opened in 1863 and closed down in 1963. It was part of the Brecon and Merthyr Railway line and, at 1,313 feet above sea level, was the highest tunnel on the UK railway network. Now it is disused but is often used as part of team building and adventure walks by local activity providers. If you are thinking of using it, you will need wellingtons (which will just about keep you dry) and a head torch. It is a brilliant place to lead a group of kids through and jump out to scare them half to death.

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

You can expect challenging sections with steep ascents, rocky paths, and potentially wet or slippery surfaces, especially near waterfalls. Good hiking boots are essential.
While the core mountaineering routes focus on higher elevations, Ystradfellte is renowned as "Waterfall Country."

These are often strenuous hikes with steep sections and steps.

While many mountaineering routes in Ystradfellte are strenuous, there is one easy route available. For families, it's important to consider the rugged and often steep nature of the trails, especially around the waterfalls. Always check the specific route details for distance, elevation, and difficulty to ensure it's suitable for all members of your group.
Many trails in the Brecon Beacons National Park are dog-friendly, but it's crucial to keep dogs on a lead, especially in areas with livestock or near steep drops and waterfalls.

The area is highly rated by the komoot community, with an average score of 4.8 stars from over 10 reviews. Reviewers often praise the dramatic landscapes, the challenge of the ascents to peaks like Pen y Fan, and the unique experience of exploring a region rich in waterfalls and natural features.
While popular peaks like Pen y Fan can attract crowds, exploring routes that venture slightly further from the main car parks or those focusing on areas like Craig Cwareli might offer a quieter experience. The Craig Cwareli – Fan y Big loop from wild camp is a moderate 15 km route that provides a different perspective of the landscape.
Spring and autumn generally offer pleasant conditions with cooler temperatures and beautiful scenery, though paths can be wet. Summer provides longer daylight hours but can be busy. Winter mountaineering is possible but requires appropriate gear and experience due to potentially icy conditions, strong winds, and reduced visibility on higher ground.
Public transport options to the more remote starting points for mountaineering routes in the Brecon Beacons can be limited. While Ystradfellte village itself has some bus services, reaching specific trailheads often requires a car. It's advisable to check local bus schedules in advance if you plan to rely on public transport.
Many popular trailheads, such as those for Pen y Fan, have designated car parks like Neuadd Car Park or Pont ar Daf. However, these can fill up quickly, especially during peak season. Always aim to arrive early, park responsibly, and be aware that some car parks may require a fee.
