Yes, the Green Grotto is definitely worth visiting if you're in Capri or thinking of taking a trip there from Naples or Sorrento. This small sea cave takes its name from the striking emerald tone of the water and—unlike the Blue Grotto—you can actually swim there. For ease and convenience, most people choose to combine a visit to both the Blue and Green Grottoes on a wider boat tour of or from the island of Capri.

Per one customer who booked the Capri Blue Grotto Small-Group Boat Day Tour from Sorrento, "A magical day on the water around Capri, with time to fully enjoy Anacapri and Capri town, [experience a] serenade in the Blue Grotto, and an April swim in the turquoise waters offshore. Rafaela was our lovely captain who went out of her way to make sure we all enjoyed our time. The boat is beautiful, and the small group size was perfect."

The Green Grotto is so-called because of the emerald-green water inside the cave. This phenomenon is caused by sunlight filtering through seawater, which reflects off the seabed and the cave's limestone walls, creating a mesmerizing green glow. The combination of light and algae may also contribute.

Yes, you can swim inside Green Grotto, unlike other caves on Capri, such as the more famous Blue Grotto. The cave is relatively easy to reach by boat—whether with a group tour or private hire—and doesn’t require paid admission.

The Green Grotto is on the southern coast of central Capri, just west of Punta Ventroso. Boat tours that visit the grotto depart from Marina Grande or Marina Piccola on Capri Island. Alternatively, you can hire a private boat or join a group tour from nearby towns like Sorrento or Positano.

No, the Green Grotto has neither opening hours nor admission fees. Unlike the Blue Grotto, which often has lines of boats waiting to enter, the Green Grotto is typically less busy and relatively easily accessible. You’ll need to join a boat tour or book a hire boat to get there, however.

Not really. While it is technically possible to swim to the Green Grotto from Marina Piccola, it’s a long swim along rugged coastline and potentially unsafe. Swimming from a boat offshore is possible; the cave has two openings, though one is typically underwater.

Yes, you can take photos in the Green Grotto. Inside, the mesmerizing emerald colors refracting off the water and walls make for great photo ops—but you’ll probably need a waterproof camera.
