The speedboat slips out of Portimão’s marina and the river narrows behind you; salt spray lifts and the Atlantic dares you to keep pace. Within minutes the Arade River’s ochre cliffs and the ruined stones of São Francisco fall away, and the guide—an onboard biologist—scans the horizon with practiced calm. The boat moves into open water, engines tuned to observation rather than speed, searching for spinning silhouettes and the quick flash of dorsal fins.
