Grand Congloue - Marseille & Calanques
Grand Congloue isn’t just a dive; it’s a trip back in time, especially if you’ve read anything about Cousteau. We love dropping onto this reef, knowing exactly where Jacques and his team made their pioneering finds. The main draw is the sheer wall that drops from around 15 metres, plummeting to 40 metres and beyond. It’s covered in some spectacular red coral, thick bushes of it, interspersed with dark patches of black coral deeper down. Keep an eye out for the big dory that often hang around the ledges, and we’ve seen impressive garrupa here too, often tucked away. The deeper sections require good buoyancy and awareness, as you're navigating quite a steep face. We’d suggest going early in the morning to beat the boat traffic and catch the light filtering through the water, it’s quite dramatic. It’s an intermediate dive, definitely one for those comfortable with deeper profiles and managing their air. If you appreciate a site with a compelling story, Grand Congloue is our pick.
