This dive site, Baixa do Espelho, is a captivating volcanic reef located off the coast of São Miguel Island in the Azores, Portugal. The reef's most striking feature is a large volcanic hole with a natural arch, offering divers an exciting swim-through experience. The dive typically begins at the reef's top, which lies at a depth of 7 meters, gradually descending to a maximum operational depth of 21 meters, exploring a diverse underwater landscape of rock and sandy bottoms.
The marine life here is exceptionally varied, providing a vibrant spectacle for divers. Common inhabitants include robust groupers, colorful hogfish and parrotfish, and schools of queenfish and jack mackerel. Moray eels can be found tucked into crevices, while salemas and sea bream dart across the reef. For those with an eye for smaller wonders, the site is rich with puffins, hermit crabs, spider crabs, and intricate nudibranchs.
The best time to visit Baixa do Espelho for diving is typically during the warmer months from May to October, when water temperatures are more comfortable and sea conditions are generally calmer. This site is highly suitable for both scuba divers of all levels due to its manageable depths and for freedivers who can enjoy the arch swim-through and vibrant shallow reef. Divers should bring a camera to capture the unique volcanic formations and the diverse macro and medium-sized marine life.
