Had to walk it most of this, pushing the mountain bike. Thank goodness it was very dry. Great views, but I would not want to tackle this on a wet winter's misty day.

Devil’s Staircase is a climb for mountain bike type gears and an advantage for those that can ride out of the saddle .My attempts have failed miserably,best of luck.

The eastern and upper sections of this pass are mostly ridable in either direction on a gravel bike (fair play if you can scale the climb heading east to west!) but caution is advised if descending the western side, even on a mountain bike. The washout has only gotten worse since this highlight was created. It is now like a ravine – easily six feet deep or more in places. It's quite entertaining to push alongside, but I would strongly advise even confident cyclists to push as a fall would have serious consequences. For context, we rode (pushed, really) across this pass on lightly loaded gravel-adjacent road bikes in the pitch black and driving rain. As anticipated, it took around 1.5 hours to get from the chapel to the hostel. Finally, the hostel warden doesn't expect the road to be repaired by the council unless a grant or funding is secured by the green laning community. As such, ride anticipating the route to be as described here.

Built in 1913 the Rhandirmwyn Bridge links the two sides of the Towy valley by this rivetted girder road bridge. On the southern side you'll find the Towy Bridge Inn, a lovely riverside pub.
