Berlenga Grande is defined by a dense concentration of wrecks, caves, and walls, with almost all sites reached by boat. Beginners can explore shallow cave and wall terrain at sites like Cova do Sonho and Parede do Relaxe, while intermediate and advanced divers push deeper at wreck sites such as Vapor do Trigo, Gomes VIII, and Maroudio Inglessi. Nudibranchs dominate the marine life, with the Common Octopus and European Common Cuttlefish consistently encountered across the reef.
