The stretch of coast of Calafuria is characterized by the fusion of two different environments also in colour: high up, on the hills leading towards the Castellaccio, the green of the Mediterranean maquis of the Calafuria Nature Reserve dominates unchallenged, free from marked anthropization; below, beyond the ex-Aurelia, the intense blue of the sea dominates, in which, on clear days, you can see in the distance the islands of Gorgona, Capraia, sometimes even Corsica, and the island of Elba with Piombino promontory
Immediately before the Calafuria bridge is the homonymous tower built in the Medici era for the purpose of sighting Barbary raids. Now under restoration and cannot be visited
In the same area, up to the Calignaia bridge, there are frequent sandstone cliffs in which quadrangular spaces of various sizes were cut out in ancient times (Etruscan and Roman), probably used as stone quarries, which the sea filled in, making to become the larger pools of real swimming pools (perhaps the locality is precisely the one that the Tabula Peutingeriana reports as "ad piscinas"); here, thanks to the low level and tepid temperature of the water, it is common to see children bathing in the good season.
