Pedrinha is a marine reserve off Santa Maria, reached by boat from Vila do Porto marina and known for easy access and clear water. The reef has a shallow top and then drops through a broad platform, caves, and volcanic formations into deeper slopes, so it works for relaxed dives and more ambitious profiles. It is a strong option for night dives, snorkeling, and underwater photography, with weak currents on the published profile. Expect small fish, barracudas, groupers, moray eels, nudibranchs, and occasional pelagic rays or sunfish.
