In reply to Ramon Marin:
A further thumbs up for Ulassai. We we there in late June, bit hot but overall very impressed. Lovely village in a beautiful setting with crags surrounding it, generally walkable or very short drive to save a few minutes walking. Thought the climbing quality was really good, pretty varied though with a bias towards wall/slightly overhanging, good spread of grades with lots mid 6s to high 7s.
Only other place I've been in Sardinia is Cala Gonone, nice coastal setting and some good stuff worth visiting but more spread out and not as good as Ulassai imo.
