Forme 4 is a unique dive site in France. The site is a flooded dry dock in the middle of the port of Dunkirk. Where in the dock ships were once maintained or dismantled, divers now enjoy a beautiful underwater world. The infrastructure of the dry dock is still clearly visible, with pontoons on the surface and beautifully overgrown tools on the bottom. This makes a dive in Forme 4 somewhat look like a wreck dive in the North Sea. The dock is no deeper than 9 meters and is home to numerous species, such as black-eyed lipped fish, stonefish, eels, sea bass, tubeworms and more. Permit required.


Dive site Forme 4 has limited parking space fairly close to the entry point. Make sure you can join a permit holder. This person will call the harbor master upon arrival after which you can enter the site via a concrete staircase.


To dive in Forme 4 a permit is required. A dive must always be signed in and out with the harbor master. Dive buoy or dive flag required. Thick sediment layer. Stay more than one meter from the bottom.
