Secca del Papa is a boat-dived shoal in the Tavolara Marine Protected Area, split into two sections by a sandy channel and served by separate moorings. It is known for coralligenous walls, gorgonians, and a very high concentration of fish. This is one of the standout dives in Sardinia for divers who want strong structure, big schools, and a protected-area reef feel rather than an easy shallow swim.
