Festival Grand Océan 2023

A heritage of humanity, the ocean covers more than 70% of the Earth?s surface. But if it fascinates us, do we really know it?

For its 2nd edition, the Festival Grand Océan invites young and old to discover, reflect, participate and act in the preservation of marine biodiversity.

With conferences & debates with experts, fun & immersive activities, Grand Océan invites you to join us on September 29-30 at La Cité de La Mer in Cherbourg-en-Cotentin and on October 1, 2023 at Omonville-la-Rogue for a unique 72-hour dive to discover the seabed.
