Le Grand Bleu
Port Louis deep drift wall for experienced divers.

About Le Grand Bleu
Le Grand Bleu is Port Louis' deep drift drop-off: a wall-like reef edge that falls into blue water just off the marina. Divers follow the current along the slope, with coral growth, sponges, and schools of fish along the way. It is a site for experienced divers who are comfortable with depth, drift, and the risk of narcosis.
