commonDive profile & how the dive runs
A typical dive at Sesimbra Wreck Garden begins with a boat entry, followed by a controlled descent along a mooring line or reference point to the wreck or reef structure. Divers will navigate around the exterior of the wrecks, such as the River Gurara, observing the marine life that has colonized the artificial reef. Depth progression varies depending on the specific wreck and diver certification, generally staying within recreational limits for most explorations. The route often involves circumnavigating the structure, paying attention to details like penetration points, propeller, and bridge areas, while being mindful of buoyancy. Turn points are usually dictated by air consumption or bottom time, ensuring a safe ascent. Safety stops are conducted in the blue or along the mooring line before surfacing to meet the dive boat.
Underwater photography
The diverse subjects at Sesimbra Wreck Garden offer excellent opportunities for underwater photography. For wide-angle shots, a fisheye or wide-angle lens is ideal to capture the full scale of the shipwrecks and the expansive reef formations, especially with the good visibility often present. Macro lenses are perfect for detailing the abundant nudibranchs, octopuses, and other small critters inhabiting the wrecks and reef cracks. External strobes are highly recommended to bring out the vibrant colors of marine life and illuminate darker areas within wreck exteriors. Pay close attention to buoyancy control to avoid disturbing fragile ecosystems or kicking up sediment around the wrecks, which can impact visibility for other photographers and divers. When photographing marine life, maintain a respectful distance and avoid harassing subjects.

Safety & environment
