The engine hums, gulls wheel overhead and the Algarve unspools in layered bands of blue as the boat slips from Portimão Marina. Passengers lean on the rail, breath held, as a pair of bottlenose dolphins arcs from the wake—water daring the sky—and a multilingual marine biologist steps forward with a small, precise map of local currents. The tone is part natural-history lecture, part sea-spray storytelling: an efficient brief before the coast opens into a sequence of honeycombed cliffs and the low, cathedral mouth of Benagil.
