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.

Lovely steep dual carriageway with minimum traffic from the valley up to the sennybridge military training area. Only on Welsh mountain roads would you find this

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

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

The gravel here is really chunky, but fairly smooth when flat out on the descent. Be prepared to lift your bike over a gate at the top.
