Near the northern Necropolis, there is the Grotta dei Pipistrelli (Bat Cave), the largest natural grotto in Pantalica.
Those who enter this place no longer have daylight to guide them and must rely on their sense of hearing only. Its silence is interrupted by large drops of water falling from the stalactites and forming small puddles on the ground, and above all, by the noise of the bats, whose disorderly flight imitates the rustling of the wind.
