In reply to solomonkey:
City of Rocks (Citta dei Sassi), the boulders near Sass di Stria on the top of the Valporola pass and the conglomerate boulders on the Fedaia pass opposite the Marmolada on the Padon Ridge are all worth a look.
Some great stuff at the back of the Alpi di Suisi but it's a long approach.
Have fun!
