Recreational and sports diving, holiday diving, as well as commercial diving or special-purpose diving in Croatia are governed by the Regulations on Conducting Underwater Activities, the Labour Act and the Safety-at-Work Act.

Holiday diving can only be conducted within the organisation and under the supervision of a diving centre that is authorised and qualified for recreational and holiday diving. The place of diving must be visibly marked with a dive buoy or a floating dive flag. The telephone numbers of the Search and Rescue Service and those of hyperbaric chambers must be clearly displayed in all dive centres and on all dive vessels.
