A low afternoon sun slants across the black basalt ramparts of Aci Castello as divers rig their scooters on the quay, the sea smelling faintly of brine and volcanic rock. Slip beneath the surface and the current seems to push you forward, sending you along a corridor of lava pillows, basalt columns and pale sand; schools of sea bream part like curtains to let the scooter pass.

Bring your certification card

Check visibility windows
Midday and calm seas usually provide the best visibility over the lava formations—plan dives around local weather forecasts.
Secure loose items
Underwater scooters increase speed—strap down cameras and remove dangling gear to avoid entanglement or loss.
Respect the protected area
Do not touch marine life or disturb the seabed; the Cyclops marine area is ecologically sensitive.
Mask and low-volume snorkel
A well-fitting mask improves sightlines when transitioning between breathing cycles; a snorkel is useful on the surface.
