Four kilometres west of Amalfi, this grotto is named after the eerie emerald colour that emanates from the water. Stalactites hang down from the 24m-high ceiling, while stalagmites grow up to 10m tall. Buses regularly pass the car park above the cave entrance (from where you take a lift or stairs down to the rowing boats). Alternatively, Coop Sant’Andrea runs boats from Amalfi (€10 return, plus cave admission). Allow 1½ hours for the return trip.
Each year, on 24 December and 6 January, skin-divers from all over Italy make their traditional pilgrimage to the ceramic presepe (nativity scene) submerged beneath the water.
