Thanks guys for filling in the blanks.
Onto Teruel, and the Spanish Renaissance aquaduct there,

after which we headed northwest towards Albarracín on the N-234 then the A-1512 (this is a straight road across a plain and the wind howls across it so fast we had to ride at about 70 degrees so as not to be blown off our bikes).
That took us to Gea de Albarracín, and then Alabarracín itself as was mentioned is worth going to see.
As was said, there are several ways around this area, and they're all stunning.
At this point, last year we took the A-1703 and then the A-1704 past Calomarde, and Frías de Albarracín, basically to the crossroads that enters the Cuenca national park.
However, a few years ago, I took the A-1512 northwest instead of turning onto the A-1703 and this road, along with the turning back south onto the TE-V-9032 is a much smaller, rougher and less well-travelled road, where I think we rode for about an hour without seeing anyone at all, that'll be this year's tweak.
This takes you past Guadalaviar where there is a small and for some an interesting museum about how people migrated their livestock across the country

Eventually, there is a T junction which meets with that alternate route (A-1704) mentioned above. This is the equally remote and rough tiny road, the CM-2119 that enters the Cuenca national park.
Once in the park, head south on the CM-2106, then southwest on the CM-2105, following this road through the park until the junction with the CM-2104 where you could head south to see the Ciudad Encantada. The only thing about these strange stones that the wind has carved into strange shapes, is having to leave the bike unattended, and pay the entrance fee.

After this you could continue onto the same road until it enters the CM-2105 and onto Cuenca itself and see the hanging houses that were mentioned before.
My choice at the junction off the CM-2105 and the CM-2104 is to stay on the former and go to the viewpoint at Ventano del Diablo

Carrying on this same road if you're camping, is a nice campsite just before Cuenca.

However, my tweak this year for the adventurous among us, if I could take you back to just a few miles into the Sierra de Cuenca (Serranía) on the CM-2105, there's a turning to the right signposted Las Majadas (Los Callejones as a place of interest in brown).
This is another remote road that leads to a mini version of the Ciudad Encantada (Enchanted City). The downside, if you choose to follow their road signs is that there's a 20km/hr speed limit, but I very much doubt it's policed.
I haven't been there but it's a smaller version of the Enchanted City so I'm presuming with less people around, a bit more secure, but completely free of charge and happily less crowded.
After the end of this small road it rejoins the CM-2105, I would go back a kilometer or so to see the viewpoint at Ventano del Diablo and then continue back to Cuenca.
