The waters are home to diverse marine life, including over 200 species of coral, sponges, large schools of fish and giant nudibranchs.
The best dive sites are in the north, around the Seven Brothers islands. These remote uninhabited islands lie in the narrow Bab El-Mandab straits, which marks the southern entrance to the Red Sea. A range of superb dive sites offers some of Djibouti's most bio-diverse diving. Strong currents (so advanced divers only) and extremely fine corals are a feature of many of the dives around the Sept Freres. Visit from mid-October to late January and you have chance to see the extraordinary whale sharks.
Between September and January, it is home to resting migrating whale sharks. It is common to see many whale sharks including juveniles who stay within the safe confines of the coast line.
