From the entry near the small lighthouse, follow the shoreline and pass under the Lafarge quay (Bordelaise pontoon) between the pillars, then return along the opposite bank: sheltered route, shallow depth.
A lively lagoon site: long-snouted seahorses, nudibranchs, pipefish, cuttlefish, anemones, ascidians and fan worms on seagrass beds and artificial structures.
