Ania is the hamlet of Serra di Fiumorbu, ensconced in and surrounded by the maquis and greenery, located at the end of a small cul-de-sac (D45). Beneath the hamlet lies a rocky outcrop on the side of the path. At its summit, you can see the gigantic trough cut in the stone. On this site, running alongside the rocky outcrop, the Circinellu grotto (visitors welcome). A Roman road flanks the mountain, north-east to south-west, passes through U Lugu di Nazza, U poghju di Nazza, Isolacciu and San Gavinu and finishes up at the hamlet.
