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.

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.

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.

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