Discover the Calanques seabed

The Calanques, the exploration ground of pioneers such as Georges Beuchat and Jacques-Yves Cousteau, saw the birth of modern scuba diving. A history whose richness is equalled only by the National Park's sea beds and cliff-faces!


Best practices

  • Use the mooring buoys and rings provided for divers (see below).
  • Take care not to anchor your boat on the neptune grass meadow and the coralligenous structure with the help of the Donia mobile app.
  • Respect all wildlife, avoiding intentional contact and do not feed them.
  • Keep your distance from cetaceans and do not follow them: if they change speed or direction abruptly, it means that they do not want to be approached.
  • Control your stability and avoid any contact with the seabed.
  • Take care not to hit the neptune grass meadow with your fins.
  • Take all waste ashore and recycle it.





  • Always check the weather conditions and stay aware of any changes.
  • Dive as a group and look after the members of the group.
  • Signal your presence on the surface with an appropriate flag.
  • Be aware of your physical limitations.
  • Bring water and energy snacks.
  • Ensure you have a means of communication on your boat: mobile phone, VHF radio.

The diving charter

Since 2014, a charter of good practices brings together diving enthusiasts committed to protecting biodiversity: join them!

 Ecological moorings

These moorings allow boats to tie up to a buoy fixed to the seabed rather than drop anchor. Access to the buoys is free of charge and is intended primarily for diving activities.
