Source de la Bisse - Marseille & Calanques

Source de la Bisse is a dive for those intrigued by freshwater springs meeting the sea. We’ve found the main draw is the visible thermocline where the cooler, clear spring water mixes with the warmer Mediterranean. You’ll usually see a good range of small Mediterranean fish flitting about the rocky bottom. It's a calm dive, suitable for all experience levels, particularly if you’re looking for something a bit different than a typical reef.
