Dive sites in Portugal

Situated along the rocky coast of Cascais, this dive site lies offshore from the dramatic sea-chasm formation on the cliffs above. The underwater terrain mirrors the rugged limestone topography visible from the surface, featuring submerged gullies, overhangs, and fields of fractured boulders. Atlantic swells regularly scour the rocks, fostering communities of encrusting sponges, anemones, and sheltering octopuses.

Caloura Arches sits along the sheltered southern coastline of São Miguel, offering a network of volcanic arches, overhangs, and swim-throughs formed by ancient basalt lava flows. Ambient sunlight filters through cracks in the overhead stone, illuminating sandy patches between the volcanic rock formations. The topography provides refuge for Atlantic and subtropical marine species resting under ledges or hunting across the seafloor.

Situated along the rocky Atlantic coast outside Cascais, this dive follows a rugged underwater canyon formation carved into the coastal bedrock. Steep stone walls, narrow gullies, and scattered boulders create natural channels where marine life seeks shelter from Atlantic surge.

Built as the World War II Liberty Ship SS Edwin L. Drake, the Dori sits upright on a sandy seabed off São Roque on São Miguel Island. Decades of Atlantic swells have broken the protected archaeological park down into an artificial reef where divers navigate exposed steam boilers, structural beams, and fractured hull plates sheltering marine life.
