Dive Site Location & Key Facts
Everything you need to know about this dive site.
Dive Site Overview
Secca dei due balconi unfolds as a breathtaking, vibrant oasis, often overshadowed by the nearby Amoco Milford Haven wreck. Located just minutes by dinghy from the port of Arenzano, this site is a spectacle of rare beauty, a silent forest where red and yellow Paramuricea clavata gorgonians flourish alongside white Gorgonia flabellum.
Its morphology consists of low, closely spaced rocks and vertical walls that rise dramatically from a sandy bottom at 47 m (154 ft) to shallower sections around 38 meters. These solid, hard rock substrates provide a perfect foundation for the extensive gorgonian colonies. Descending the fixed buoy line, typically anchored in the deeper areas, divers can explore the secca's amplitude, which spans approximately two kilometers.
The site is a true testament to marine life's resilience, acting as a vibrant underwater garden in waters often influenced by coastal activity. Its unique name originated from a local fisherman, Mirò, who aligned two prominent land-based balconies to mark his abundant fishing spot.

Dive Experience & Conditions
Descending into the secca, divers often encounter water that feels thick with suspended particles, at times reducing visibility dramatically, even down to a meter. This frequent turbidity is caused by the fine silt from the seabed, agitated by constant boat traffic and marine currents. Easily found currents can make navigation more demanding, particularly across the secca's fluctuating topography, which spans recreational depth ranges into the deeper end of the spectrum. The environment below can appear opaque and somewhat subdued, requiring good lighting to fully appreciate the colors. Despite these conditions, the secca's extensive coverage of gorgonians appears healthy, with polyps extended, indicating a rich planktonic environment. While there is a fixed line traversing the center, its vastness encourages exploration, making careful buoyancy and situational awareness crucial.
Dive Difficulty & Safety Guidelines
Diving Secca dei due balconi demands advanced skills or the presence of an experienced guide due to its depth and variable conditions. The site's depth profile extends well into the technical diving range, requiring advanced planning for extended bottom times. Currents are common, and visibility can be significantly reduced, sometimes to a meter, requiring strong navigational skills. Divers exploring the full breadth of the secca may need to deploy a reel to avoid disorientation amidst its undulating terrain. Using twin cylinders (bibombola) or a rebreather is advised for satisfactory bottom time at these depths. Conversely, single-cylinder dives will result in much shorter bottom times. Adhere to your specific training agency's recommendations for gas mixes, which might include light trimix, air, and appropriate decompression gases.

Marine Life at Secca Dei Due Balconi
A tapestry of red and yellow Paramuricea clavata gorgonians adorns the secca, creating stunning underwater forests that are particularly dense on the subvertical walls of the south side. White Gorgonia flabellum also thrives here. Among these vibrant corals, divers frequently observe various fish species like saraghi (sea bream), cernie (groupers), and orate (gilt-head bream). Octopuses, scorpionfish, and musdee find refuge in the rocky crevices. Anthias anthias add flashes of color, while between March and June, gattucci (catsharks) are known to deposit their eggs among the gorgonian branches. Large Sarcotragus spinosulus sponges mimic soft rocks, and yellow Aplysina cavernicola colonies color the northern slopes, showcasing a rich coralligenous community.
