Best time to dive

May to October

What you might see

Moray eelPossible

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

Certification & difficulty

Technical - advanced conditions (currents/depth); dive within your training.

Snorkelling

Not a snorkel site - No - this is a full scuba dive site with entrances at 11-30m, not a snorkel/light-penetration site

Safety notes

Overhead/cave environment - silt-out and disorientation risk in the hall and the narrow 'Chimney' tunnel; depth to 50m in the alternate tunnel; site explicitly recommended only with a guide/experienced buddy; no documented cave-certification requirement, itself a notable gap

Permits & fees

General Croatia foreign-diver permit, approx. EUR 15/year; no Premuda-specific fee found; guided dive packages at this site reported in the range of EUR 169-330 per one operator

Permits and operators change - confirm before booking.
