Dive Site Overview

Navigating the calm waters of Berlengas Island, Flandres provides a relaxed dive experience, often defined by its varied underwater landscape. Starting over a shallow sandy bottom, divers might first spot streaked gurnards camouflaged against the sediment.

From this initial exploration, the route guides divers towards a small cavern. While modest in size, this overhead environment frequently shelters forkbeards, making it a point of interest. Continuing the circuit, explorers encounter the remains of a small wreck, which has become a stable habitat for octopuses, often seen tucked within its structure.

From here, the route circles Cavalete Rock, an important feature that shapes the circuit and allows for extended bottom time. Remaining within a maximum depth of 15 m (49 ft), the entire trajectory allows for ample exploration without significant depth challenges.

Throughout the dive, schools of seabreams and cowbreams frequently move through the water column, adding dynamic elements to the scenery. Flandres presents a fulfilling and accessible route within the archipelago, particularly for those seeking a less demanding yet engaging underwater journey through a truly sheltered bay.
