Situado dentro da Reserva Garajau, a Arena tem uma formação rochosa, onde há um túnel horizontal que se liga a outro na vertical, tendo o seu topo de 7 metros e o inferior 16 metros. A entrada deste túnel lembra uma arena, daí o seu nome. Ao longo do mergulho, podemos observar golfinhos (Sparisoma cretense), peixinho (Bodianus Scrofa), pargos (Pagrus pagrus), baleia (Mycteroperca fusca) e snorers (Pomadasys incisus). No fundo da areia circundante, encontramos centenas de enguias de jardim (Heteroconger longissimus).
Baixa de Santa Catarina
The low of Santa Catarina is located in front of Santa Cruz, about 500 meters from the coast and 10 minutes from the recreational port of Machico. It is a wall covered in black coral where the top is at 13m and the bottom at 40m. Along the wall we can observe a whole panoply of fish associated with the rocky subtract like, greenfish (Thalassoma turkey), chestnuts (Abudefduf luridus and Chromis limbata), among others. On the sandy bottom it is possible to find large rays (Taeniura grabata). Being a dive away from the coast and sometimes subject to currents requires some experience, but certainly a very interesting dive, where you can observe pelagics.
The Garajau is the main dive of the Garajau Reserve and the most emblematic of the island of Madeira. It is a place of choice due to the quantity and diversity of life there, having as ex-libris the Meros (Ephinephelus marginatus), friendly animals that greet us and accompany us throughout the dive. On the rocky bottom, we find moray eels (Muraena sp.), Large anemones (Telmactatis cricoides) and various colors accompanied by their clown shrimp (Thor amboinensis), and shoals of chestnuts (Abudefduf luridus, Chromis limbata), kingfish (Coris Julis) and greenfish (Thalassoma turkey). Close to the surface it is possible to observe shoals of bicuda (Sphyraena viridensis) as well as charuteiros (Seriola rivoliana).
Baixa do Lobo
Named Baixa do Lobo, due to the possibility of sighting of the sea lion (Monachus monachus), it is a dive that starts at 14 meters and reaches a maximum depth of 40 meters on the east slope. It is a dive located in the Ponta de São Lourenço consisting of a rocky platform with walls of sharp slope that end in a sandy bottom. The walls are filled with black coral (Antipathella wollastoni) and we found shoals of Sargos (Diplodus vulgaris), Salemas (Sarpa salpa) and Roncadores (Pomadasys incisus). A dip with clear waters, where the high point occurs when we see the fur seal.
Diving located at the end of Ponta de São Lourenço, east of the island, outside the lighthouse. It is a demanding dive due to the strong currents, but when the conditions are good it is one of the best dives of the island. It is a low that starts at 3 meters and reaches 40 meters deep. At the top we find wrecks of a shipwreck, the boiler being the structure that is in better conditions. Alongside the wreck we observed several shoals, including chestnuts (Chromis limbata, Abudefduf luridus), kingfish (Coris julis) and greenfish (Thalassoma turkey). It is a very attractive dive due to the possibility of seeing large pelagics such as charuots (Seriola rivoliana).
