Crystal-clear cave visit with shallow life and light effects.
Crystal-clear cave visit with shallow life and light effects.
A local boat or dinghy support is the normal way to reach the caves.
Grotta della Maga Circe & Grotta di Capo Bianco are boat-access sea caves on the west side of Ponza beneath white limestone cliffs. The draw is crystal-clear water, dramatic light effects, and shallow-life sightings such as parazoanthus, coralligenous growth, bream, seabream, and octopus. It feels more like a calm cave-and-cove excursion than a big-depth dive, so it rewards careful timing, quiet entry, and a relaxed pace at the cave mouths.
