A heritage of humanity, the ocean covers more than 70% of the Earth?s surface. But while it fascinates us, do we really know it?
For its 2nd edition, the Grand Océan Festival invites young and old to discover, reflect, participate and act in the preservation of marine biodiversity.
Grand Océan looks forward to seeing you 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.
