The name Grotta Bianca (White Grotto) originates from the high concentration of white calcium carbonate deposits covering the cave walls.
The cave is physically separated into two distinct levels connected by a natural limestone chimney.
The lower section of the cave is partially submerged, allowing small boats to enter during calm sea conditions.
The unique color of the water inside is a result of light refraction caused by the cave's white walls and sandy floor.
Grotta Bianca, located on the northeastern coast of Capri, is a sea cave named for the striking white limestone stalactites and stalagmites that line its interior. The cave is divided into two levels, with a lower cavern accessible by boat and an upper gallery featuring significant crystalline formations. Light reflecting off the sea floor creates a distinctive aquamarine glow within the lower chamber. The cave is situated near the Salto di Tiberio cliffs. Visitors typically reach the site as part of a coastal boat tour of the island. It is frequently visited in conjunction with the nearby Grotta Verde.

Coordinate your trip with a boat operator who includes the cave in their standard island circuit.
Verify sea conditions with your captain, as high swells can prevent entry into the cave mouth.
Use a polarizing filter on your camera to capture the water clarity without glare.
Do not attempt to swim into the cave independently, as boat traffic in the narrow entrance is constant and hazardous.
Access is highly dependent on sea and weather conditions; tours typically operate from spring through autumn.
Avoid touching the stalactites to prevent oils from damaging the delicate mineral formations.
