Ambrósio
Protected offshore seamount famed for summer mobula encounters.
ScubaSnorkelBoat EntryIntermediate

Local operator required
The site is reached as a guided boat trip from Santa Maria rather than by independent shore access.
Boat-only reserve off Santa Maria where divers usually work from the line in open water for mobulas, with strong visibility but Atlantic current and weather deciding the day.
About Ambrósio
Ambrósio is Santa Maria's signature offshore reserve, a compact seamount in blue water where mobula rays, jacks, barracuda, tuna, and other pelagics gather through the warm-season run. Most dives focus on staying close to the line above the reef and letting the action come to you rather than touring a sheltered reef edge. The site is reached by boat from Vila do Porto and feels exposed to Atlantic conditions, so days are built around weather, current, and skipper judgment. When it settles, Ambrósio delivers one of the island's most reliable big-animal experiences and can also suit confident snorkellers hoping to watch mobulas pass in the upper water column.
