Ses Orgues

The park's own underwater-itinerary chart plots a shallow shelf close to shore, from about 6 to 13 metres, where a Posidonia patch grows on the western side and the mooring buoy sits at 13 metres.1 From there the ground steps down through 20, 30 and 35-36 metres to a mapped 40 metres off the point and along the eastern islet chain. The route as guided works a single deep profile: one Cadaqués operator describes it as a pre-coralligenous corridor leading into coralligenous communities around 40 metres, and the region's eco-guided dive-route registry gives the working band as 35 to 43 metres and rates the whole route Expert, consistent with a dive that spends most of its time well below 30 metres rather than circling a shallow reef.

An abandoned mica mine, the Mina de ses Orgues, sits on the cliff directly above this dive. An aerial-photo analysis shared in a hobbyist mineral-collecting forum tracks the cliff's pegmatite dike: narrow at the top, wide at sea level, and, the analysis notes, apparently narrow again in the submerged section. The dive is the underwater continuation of the same seam the mine once worked, not a separate feature that happens to share a name. The park's own itinerary sheet illustrates six species for this exact point: the Mediterranean slipper lobster, the parasol-shaped green alga Acetabularia acetabulum, the sacoglossan sea slug Elysia timida, common octopus, Mediterranean moray and marbled electric ray.1 Tagged (RNP) on that same sheet, the site sits inside one of Cap de Creus's three marine Partial Nature Reserves, though the sheet itself does not say which.

Access is by boat from Cadaqués only; no shore-entry option is documented. Because the guided route has no shallower fallback, decide your gas and no-decompression limits for the full 35-43 m working depth before you leave the surface. At that depth this dive works well below the area's own summer thermocline, close to 15 metres, where bottom temperatures drop toward 14°C: budget for a heavier exposure suit than the area's shallow-water default. Night diving between sunset and sunrise needs special park authorisation here, and initiation, first-level or baptism dives are barred in the park's no-fishing sectors.2 Independent divers must give the park prior notice and stay within its cap, applied per boat, not per diver: six dives a day, thirty a week, a hundred and twenty a year.2
