Grotta di Nettuno
Meilleur moment pour visiter
Visit late morning (10-11 AM) when the sun is high enough to illuminate the cave's interior through its underwater opening. May through September offers the calmest seas and the most reliable boat access if you want to skip the stairs.
Conseils budget
Entry costs around 14-16 EUR for adults; children under 6 enter free. A combined ticket with the nearby promenade ferry (5 EUR one-way) saves you from climbing back up those 654 stairs.

À propos
Faits rapides: Creusée par les vagues pendant des millions d'années, cette grotte marine s'étend sur 120 mètres de profondeur et atteint 30 mètres de hauteur à l'intérieur. Son nom vient du dieu romain de la mer, et les visiteurs atteignent l'entrée en descendant 654 marches taillées dans la falaise.
Points forts: Lors des calmes soirées d'été, la lumière du soleil filtre à travers une ouverture sous-marine, créant une lueur turquoise irréelle sur les parois de la grotte. La grotte abrite une population de rares crevettes blanches des cavernes qui survivent dans l'obscurité totale, visibles seulement quand la lampe d'un guide capture leurs corps translucides dérivant dans l'eau.
