You feel the boat rise and fall like a quiet animal beneath you as the marina slips behind—white masts, tile roofs, and the distant stretch of Praia da Rocha. The skipper eases the low-profile vessel into the open sea and the cliffs of the Algarve tighten around you: honey-colored limestone, scalloped mouths carved by wind and wave. Within minutes the coastline begins to deliver what postcards promise—arched caverns, hidden blowholes and the small, sunlit hollow of Algar de Benagil, its circular skylight throwing a pool of light onto the sandy floor.

History
The Algarve coast formed as limestone uplifted and eroded by Atlantic swells over millions of years; many sea caves are the product of tidal abrasion and roof collapse.
Conservation
High visitor numbers strain fragile cliff ecosystems and cave interiors—stick to crew guidance, avoid touching rock formations, and pack out all waste.

Arrive Early to Board
Get to Wooden Kiosk No. 3 at Portimão Marina at least 20 minutes before departure to check in and secure a good seat on the low boat.
Bring a Dry Bag
Protect phones and cameras from spray—boats are low and close to cave mouths where waves can splash unexpectedly.
Sun Protection on Deck
Sunscreen, a brimmed hat, and sunglasses matter—reflected light from the cliffs intensifies sun exposure even on breezy days.
