L'Atelier de la Mer · Pointe Rouge, Marseille
A dive centre in Marseille's Pointe Rouge harbour kits you out in a wetsuit, mask and fins, then runs you 20 to 25 minutes by boat to a snorkel site picked for the day's conditions. It's the trip for people who want to look under the water, with instructors, rather than at the cliffs.

L'Atelier de la Mer is a dive centre in the Pointe Rouge harbour, in the south of Marseille. You arrive, change into a wetsuit (full or shorty, and mandatory on the boat), collect fins, mask and snorkel, and listen to a briefing on safety and on what lives in the water. Then a 20 to 25-minute boat ride takes you to the day's site.
Which site depends on the wind, the swell and the visibility. The listing names the Riou archipelago, Planier island, Frioul and Maïre as options. Two of those, Planier and Frioul, are outside the mainland calanques, so don't book this to see cliffs and coves. Book it for what's under the surface: seagrass, rocks and fish in a marine park where large areas are no-take zones.
Staying on the boat is allowed if you change your mind. Back at the centre there are hot showers, changing rooms and a coat check, which beats drying off on a bus. The listing rules out children under 8, pregnant guests and anyone with heart or breathing problems. Bring biodegradable sunscreen; fishing, alcohol and feeding the fish are not allowed.
