What you might see

  • BarracudaPossible

Sightings are seasonal probabilities, not promises - even in peak season nature does its own thing.

Certification & difficulty

Advanced Open Water - advanced conditions (currents/depth); dive within your training.

Snorkelling

Not a snorkel site - Limited - this is primarily a boat-based scuba site; surface hot-spring snorkeling is more associated with the neighboring islet of Palea Kameni, not Nea Kameni's dive sites

Safety notes

Heavy tourist-boat traffic in the caldera around Nea Kameni; localized thermal vents/gas seeps; variable visibility from sulfur particulates; Nea Kameni is part of an active (monitored) volcanic system; depth at the deeper sites approaches Advanced Open Water limits

Permits & fees

No specific scuba permit was found for boat-based diving that doesn't land on the islet; hiking on Nea Kameni itself requires a separate landing/entrance ticket (a few euros, general knowledge, not confirmed for divers). No archaeological-wreck restrictions apply to this volcanic site

Permits and operators change - confirm before booking.
