Caverna da Sapata
Depth is the range from the top of the site to its usual maximum; "recommended cert" is the mainstream-agency level operators usually ask for, not a legal rule. Currents and visibility change daily — treat everything here as planning ranges.
At the island's dramatic southwestern tip, where the cliffs of Ponta da Sapata drop straight into deep water, a broad cavern opens at the base of the wall. The dive stays honest cavern rather than cave - the exit remains visible in daylight - but the atmosphere is complete: nurse sharks resting in the gloom, lobster antennae fencing from the cracks, big-eye soldierfish stacked under the ceiling, and the blue mouth framing every diver's silhouette on the way out. Outside, the wall itself carries turtles and passing pelagics. Exposure to swell makes this a calm-season dive, briefed carefully and skipped without apology when the ocean says no.
The moment you come for: A daylight cavern in a sheer volcanic point, resting nurse sharks, the framed blue exit

Know before you splash
