Le Messerschmitt 109 is a Second World War aircraft wreck resting on a flat sandy seabed at a depth of 45 metres off the coast of Île Maïre. This site is strictly for advanced divers, as the depth requires careful management of nitrogen narcosis and mandatory decompression stops. Visibility at the site ranges from 10 to 30 metres, allowing for a clear view of the aircraft profile. Currents are typically mild. Due to the depth and the need for decompression, boat access is required and divers should use a shot line rigged directly to the wreck to conserve bottom time.

Le Chaouen is a prominent wreck dive located off the Île Maïre near Marseille. This artificial reef rests at depths ranging from 12 to 43 metres, with an average depth of 28 metres. Access to the site is strictly by boat. Divers encounter mild currents and visibility typically between 15 and 30 metres. Due to the nature of the wreck, the site presents hazards including deep water, potential entanglement, and overhead environments. While the site is accessible to beginners, the depth and wreck structure require careful planning and appropriate training. Water temperatures fluctuate between 12C and 17C throughout the year.

The Dalton is a 70.5-metre cargo ship that sank in 1928, resting at depths between 15 and 33 metres near Île Maïre.
