Baixa do Boi is a boat-access reef around a small isolated islet near Janela on Santo Antão. The dive starts on the protected western side of the islet and follows the rocky edge with the blue water always in view, so it feels more like a route-led Atlantic reef than a sheltered bay dive. It is a solid choice for divers who want structure, fish life, and a clear turn-around plan rather than a casual shore hop.

Snorkeling
