Grotta di Nettuno
Bedste tid at besøge
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.
Budgettips
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.

Om
Hurtige fakta: Denne søhule, udskåret af bølger over millioner af år, strækker sig 120 meter dyb og når op til 30 meters højde indeni. Dens navn kommer fra den romerske havgud, og besøgende når indgangen ved at gå ned ad 654 trin hugget ind i klippesiden.
Højdepunkter: På stille sommeraftener filtreres sollys gennem en undervandsåbning og skaber en overjordisk turkis glød på hulens vægge. Hulen huser en bestand af sjældne hvide hulerejer, der overlever i totalt mørke, kun synlige når en guides lommelygte fanger deres gennemsigtige kroppe, der driver gennem vandet.
