Me & a mate did most of the areas in that E bloc this year. As we were on a road trip most areas were done as a 1 or 2 day trip dependant on what we thought, but some areas are small. Being grade slags we aimed for Font 7a or above, but had a good look around searching for the best problems to get involved in. I found the grading went from stiff as to soft as sin. For what it's worth here's what I think. Oh I'm also sat in Oz now so going from memory. Lastly I know some of the areas I mention are lower down, but I have nothing better to do right now.
Targasonne. A good & large area. Gets hot, but Lot's of shady spots. The E bloc only covers a fraction of it. The full guide is about 35+ euros from the local campsite. Worth a look for sure.
Savassona. I thought it was pretty cool. Small & Lot's of tree cover. Some clip up stuff & would think it's OK for kids. As stated bit Font like, but not half as good.
Saint Joan de Vilatorra. Fucking hot! In a more open forest. Loads to go at some cool highish stuff. Probably not the best with young kids. Good spread of problems from cracks- overhangs.
El Cogual. The areas are spread out & mainly out in the sun. Some cool stuff, some easy to get to others a bit of a walk. Can be stupidly hot!
Albarracin. The stand out area no wonder it gets all the rave reviews! Lot's & Lot's to go at. Watch out for bird nesting restrictions thou. Get in now before it gets fucked up. There is also some history to the place like super old stone paintings if you wanna' send the kids on a walk...
Navalosa. Can't think to much on this one. As I recall a nice setting, but not much worth doing.
Burguillo. As above really. Think it was by a lake or some water setting, very pretty setting. Poor rock I think.
El Escorial. Pretty neat place. I think I found the grades stiff there. Mainly in the trees. Again a nice walk out.
Zarzalejo. Open & shit crumbly rock. Not worth the walk.
