The area is particularly noted for its cephalopods and nudibranchs. Common Octopus and European Common Cuttlefish are observed across virtually all sites, while Crimora papillata, Felimare Cantabrica, Giant Doris, and Rudmania Purpurea are among the most frequently recorded sea slugs. Fish life includes African Striped Grunt, White Seabream, Wrasses, and the well-camouflaged Black Scorpionfish, with Velvet Swimming Crab, Blue Crab, and Brown Crab commonly found on the reef.
The majority of sites are rated for beginners, covering a wide range of reef, wall, and artificial reef formations at accessible depths. The main Santa Eulália site even allows shore entry, removing the need for a boat on a first visit. More experienced divers can step up to Balanciais Fora or Faro A, which offer deeper drop-offs, caves, and a deliberately sunk wreck.
Most sites require a boat, and the area is well served by operators including Easydivers Dive Center, Wahoo Diving, Albufeira Dive Centre, Indigo Divers, and several others based locally. The main Santa Eulália reef is the notable exception, offering a direct shore entry that suits independent or budget-conscious divers. Booking through one of the local operators is the most straightforward way to reach the wider selection of offshore reefs and walls.
The concentration of artificial reef structures alongside natural reef is a defining feature, with sites such as ART Reef, Santa Eulalia 2, Pedra Da Oura, and the deliberately sunk Faro A wreck all contributing to habitat variety. This mix supports an unusually rich nudibranch community alongside the resident cephalopods. The range of depths across the sites also means beginners and intermediate divers can progress through the area without needing to travel far.
