Grotta di Nettuno
Bästa tid att besöka
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
Snabba fakta: Uthuggen av vågor under miljontals år sträcker sig denna havsgrotta 120 meter djup och når höjder på 30 meter inuti. Dess namn kommer från den romerska havsguden, och besökare når ingången genom att gå ner 654 trappsteg uthuggna i klippväggen.
Höjdpunkter: Under lugna sommarkvällar filtreras solljus genom en undervattensöppning och skapar ett overkligt turkost sken över grottans väggar. Grottan hyser en population sällsynta vita grotträkor som överlever i totalt mörker, synliga endast när en guides ficklampa fångar deras genomskinliga kroppar som svävar genom vattnet.
