6-18 m

Level

Beginner to Intermediate

Access

Rocky coastal reef and cove area west of Portimao, used only when swell, visibility and local boat logistics are suitable.

Best season

Best in settled Algarve sea states, especially calm mornings from late spring through autumn.

Safety

Surge, beach traffic and boat movement require a local briefing, conservative route choice and surface signaling.

Hours

No fixed public hours. Boat departures, protected-area access and shore entries depend on operators, permits and sea state.
