S'Adolitx

The boat run is short, around fifteen minutes south from the harbour, and the islet shape gives itself away from the surface: a chunk of dry rock standing about 12 metres above the water, south of Port Salvi. Underwater the seabed slopes smoothly off the islet to roughly 24 metres, so the dive becomes a depth-of-your-choosing loop around the rock. The pre-coralligene face carries the small Mediterranean macro the area's centres point out — porcelain-shell molluscs sitting on the rock, anemones with Periclimenes shrimp inside, the occasional moray in a hole. Around 14 metres, between the islet and the coast, La Cuarta cueva runs about five metres E-SE; centres open it to advanced divers and note juvenile spiny lobsters as the routine sighting. Down at the deepest point, around 24 metres, the white sand opens out from the base of the rock and rays and electric rays cross between rock and posidonia. The dive ends shallow on the islet shoulder for the safety stop, where slow work tends to reward you with one more macro find.

S'Adolitx reads as the area's easy rotation site rather than a signature dive, and that is the point. The two centres that name it on their site lists frame it the same way: a small visible islet, smooth descent, all levels welcome. What separates it from sibling rocky reefs in the cluster is the short tunnel at 14 metres and the white-sand surrounds where rays cross — the pairing of overhead taster and sand-edge wildlife on a single easy dive. It pairs naturally with Tuneles de Port Salvi or La Llosa de Sant Feliu when centres want a shallower second dive after a deeper morning. The pre-coralligene rock is the bottom story: an intermediate community between photophilic algae and true coralligenous assemblages, the kind of substrate that holds the area's typical macro at depths a beginner can reach.

Pick your depth at the start. Shallow at 3-12 metres is the islet shoulder and small life. The 14m tunnel adds the lobster crevices and a brief overhead — wide enough to swim through and only about five metres long, but trim and exit awareness still apply. The deeper sand edge at 20-26 metres is where to drop for the rays before climbing back up. Boat traffic at the surface is the operational hazard: this is a popular Sant Feliu entry/exit zone. Carry an SMB and deploy it before ascending. Plan exposure suit for the typical bottom range, not the surface reading: the summer thermocline at about 20 metres puts the working depth several degrees below the warm surface number from May onwards.
