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.

As you descend to this section to the viewpoint I've shared, please be aware that you have rocks and drops to descend that can be slippery when they are wet.

Gap Road. This was the first track to enable horse-drawn carriages to cross the mountain range. It's thought to be a Roman road, although no archaeological evidence has been found as yet. Turn right onto the gap road and follow this route all the way back to the car park, and to your starting point.

The Brecon Beacons well known “THE GAP” is a passing between Crybin and Fan y big in the shadow of Pen y fan. Gap Road which will take you through the Neuadd valley. The Gap Road- is actually an old main Roman road. The Gap provides the first encounter with what I call engineered paths.

Great views and riding I've only done it on gravel bikes ascending from the south. It's doable fully loaded too. The Brecon descent is proper big gravel and under biking fun. Or do it flat out on an MTB too.

The climb up to the saddle could be done on a hardtail but would recommend to ride from the saddle towards Brecon on a full sus

If you are riding a 40mm tyre, loaded gravel bike, I would say the majority of this 5km or so section (not just the lumpy bit near the top) will be easier to walk so bear that in mind if you are attempting it. It’s generally pretty lumpy the whole way and a doable challenge if you are technically good… but you’ll be walking if you aren’t… or if you already have 80km of gravel in the legs like us!! Even a guy we passed on a full sus EMTB had to hike a bike some sections as they aren’t possible to ride. I personally thought we might have an hour of hike a bike… but that quickly turned closer to 3. Absolutely stunning views, a real adventurous challenge. Would like to go back with some chunkier tyres and maybe some suspension!
