Baixa do Ambrósio is an offshore seamount north of Santa Maria known for summer mobula encounters and wide-open bluewater diving above a small rocky platform. Most dives focus on the mooring line and upper water column where pelagic life often gathers, while the deeper crest rewards experienced divers when current and surface conditions stay manageable.

Hazards, restrictions, and access requirements.
Key Hazards
Safety Notes
This is an offshore bluewater dive where current and surface conditions can change quickly. Stay with the guide or line, carry an SMB for open-water ascents, and treat deeper exploration as an experienced-diver option only when conditions are settled.
Access Restrictions
Access is by boat only and typically arranged through local operators or private boats with prior planning. Protected-area use rules can limit simultaneous vessels and diver numbers on site.
Legal Notes
Baixa do Ambrósio sits inside a protected marine area around Santa Maria. Check the current regional rules before private-boat visits because use, navigation, and fishing restrictions apply.
Community notes to help plan your visit.
Scuba Diving
Shallow depths make it suitable for divers of all experience levels.
Freediving
Freedive visits are possible by boat when surface conditions are calm and operator support is available. The site is best suited to disciplined bluewater teams that can work safely around current and drift.
Snorkeling
Snorkeling is feasible on suitable weather days because activity often happens high in the water column, but it remains an offshore boat-based trip that depends on calm surface conditions and guided support.
