Port'alga is an old fishermen's cove on the Polignano a Mare coast and the starting point of a shore dive along walls and rockfalls. Divers go for the sponge-lined grottoes and the chance of finding Flabellina nudibranchs.
Also known as Porto Alga, Portalga, Port'alga parete destra, Cala Port'alga.
Where it is and how deep
40.9914° N, 17.2391° EApproximate position — the dashed circle shows where the site lies; your operator's briefing has the mooring.
The dive
The route heads out of the cove and follows attractive walls and small rockfalls that hold many forms of life, reaching a maximum of 30 m. Along the way a few submerged grottoes are lined with brightly coloured sponges, and with a little luck a Flabellina nudibranch turns up.
