In reply to Paulos:
I've never been to Costa Blanca so hard to compare. In general, Siurana fits what you prefer. The 2 main valleys are within walking distance of the campsite and with some sectors literally 5 minutes walk in from the camp site.
If you enjoy shorter more powerful routes, check out sectors La Olla, La Trona where at those grades you'll find loads to play at! In terms of crimping wall climbing - that's what Siurana is famous for really. Espero Primavera has some of the finest routes that fit the bill, quite long though - generally 30 meters.
In general the climbing there seems to me more "British" compared to other Spanish venues as it's often cruxy and hard to read (hence hard to O/S, at least for me).
Truly stunning surroundings.
Having said that, Costa Blanca seems amazing from what I've seen in articles and photos, and I'm sure you could have a blast there as well.
