This dive site, Mamas / T-Reef, is a prominent feature within the Underwater Natural Park of Madeira, renowned for its unique volcanic topography. The site is characterized by two impressive volcanic pinnacles that ascend dramatically from a depth of 30 meters to just 12 meters below the surface. Divers typically navigate around these majestic structures, exploring their numerous crevices and ledges, which provide ample shelter for various marine species. There is no specific historical event or story provided for the naming beyond its identification as T-Reef, likely due to its shape or mapping.
The Mamas / T-Reef teems with diverse marine life. Numerous species of Moray Eels are frequently spotted, finding refuge within the intricate crevices of the volcanic pinnacles. Large schools of Barracudas are often observed patrolling the open water around the reef, alongside impressive schools of grey trigger fish. The sandy areas and base of the pinnacles are home to Sting Rays and graceful Eagle Rays, adding to the site's allure for encounters with larger pelagic species.
The Mamas / T-Reef offers excellent diving conditions generally year-round, though specific marine encounters may vary seasonally. The main highlights are undoubtedly the dramatic volcanic pinnacles themselves and the abundant large fish life, including barracudas and rays. For freedivers, the pinnacles rising to 12 meters offer excellent depth targets for breath-hold diving, allowing exploration of the upper reef without full scuba gear. Scuba divers should focus on exploring the full depth range, paying close attention to the crevices for moray eels and scanning the blue for passing pelagics. Good buoyancy control is recommended for navigating around the pinnacles.
