The boat peels away from Ponta Delgada and the island’s slate roofs shrink into a postcard. The harbor exhales a salt-scented breeze; small fishing boats bob like nodding heads. By the time the shoreline is a thin green ribbon, the sea has already changed its mood — a bright, quickening blue that seems to wait for something to arrive. Then the first spray appears, a punctuation mark against the horizon. A dolphin breaks the surface as if testing the air, then another, and soon the water offers a choreography: flashing backs, playful arcs, a pod deciding whether to invite you into its world.

A well-fitting mask and snorkel increase comfort and visibility during encounters.
