Had a big off when a rut jumped out of nowhere. To be honest, I'm glad I had 2.4 tyres for most of Strata Florida right from the road.

It's going to climb!

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.

Recently dressed with slate. I would no longer recommend road tyres through here. Something a bit wider recommended!

More stunning forestry gravel that links the Tregaron mountain road over towards Tyn y Cornel hostel.

This is currently closed to vehicles (hence all the Road Closed signs!) but is passable and fun by bike. You’ll almost certainly need to hike-a-bike the part with significant flood damage in the middle but it’s some of the finest wilderness in Wales!

An incredible stretch of road. Very isolated. Watch out for Land Rover gangs racing up to the Florida Strata road.
