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 was a truly stunning spot to take in the scenery from this elevated panoramic viewpoint. Highly recommended.

A short climb up from the road brings you to the Dam and carpark, there is no access over the Dam itself. But you do get a good view over the spillway and valley below.

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!

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.

An Elenydd Wilderness Hostel. A simple and friendly hostel, hidden away in it's own secluded valley. Hot showers, loads of bunk beds and self catering kitchen. A really lovely place to stay.
