Why dive here
With 157+ marine species recorded in the area - including blue sharks, dolphins, dwarf minke whales, humpback whales and mobula rays (devil rays) - Baie dès Milliardaires offers some of Marseille & Calanques's richest diving. Water ranges 14-25°C, warmest July, August, September.
Baie des Milliardaires is one of those spots that just feels good to be in, even before you drop in. Down below, it’s a gentle introduction to the Calanques, a calm, shallow bay that rarely throws up any surprises. Think sunlight dappling through the water onto a sandy bottom, with small schools of damselfish darting between the rocks. It’s perfect for new divers finding their buoyancy or for an easy second dive, a nice, relaxed way to spend an hour underwater. You’ll spot the usual Mediterranean suspects, sea bream, perhaps an octopus tucked into a crevice if you look closely. A chill dive, really.
