Hidden deep in the Valle di Lanaittu is the must-see Grotta Sa Oche & Su Ventu, two caves linked by a natural siphon. The former is a wild and enchanting cave named ‘Cave of the Voice’ after the water that gurgles in its secret underground caverns; the latter has some wonderful stalactites and stalagmites, and was a hideout for notorious Sardinian bandit Corbeddu in the late 19th century.
