Since this thread has resurfaced, I'll add a quick tuppence worth now I've been there.
A good little area, certainly worth a 3-4 day trip, possibly combined with the sports climbing at Siurana, Monsant etc. As Dyl said, it's got everything. Every angle, every type of hold (except tufa I suppose). Very quiet place too, we only met a handful of other climbers and all at the weekend. During the week it was empty of everyone, not just climbers.
I'd say that you'll get the most out of this trip if you can climb font 6b and above. There's plenty of hard projects left to climb and many of the 6b's or 6c's are clearly at least font 7a. Like in many quiet areas, the grades are all over the place so best to ignore them. Weather was good, very dry but sometimes too hot (even in February). In fact the best day was a showery day (like two ten minute light showers) that stayed overcast.
