In reply to cavemancolumbus:
If you have the guide it shows some multi pitch climbs at Margheddi. I tried one there called non-stop. Definitely avoid that - from my log book "Did the (long) first pitch with no gear other than a crappy thread. Then abbed back down off a rotten tree at the 'ab station' as there didn't appear to be any gear above it as well." I still remember that nearly three years later!
From memory we did find quite a lot of single pitch to do and the odd 2 or 3 pitch climb. As pointed out above the bolting is generally good and the grades are a little soft compared to say portland.
I have the pietra di luna guide and I think i also picked up a local guide from here -

The guy in the climbing shop was friendly and had the topo for sale. Good icecream nearby as well!
