This dive site is located in front of the historic harbor of Pianosa Island, marked by Buoy 2. It features submerged rocks rising from a Posidonia seabed, creating a visually stunning underwater landscape. The rocks provide shelter for various marine life and offer interesting navigational points for divers. The site is easily accessible by boat and moorings are available at the buoy.
The diverse marine life includes large groupers as permanent residents, while snappers, barracuda, and amberjacks are commonly seen during the spring and summer months. The passage of large tuna is also possible. Posidonia meadows are a prominent feature, supporting a variety of smaller organisms.
The best time to visit is during spring and summer (May-September) when the water is warmer and visibility is typically best, and larger pelagic species are more prevalent. Divers should be aware of potential currents around the rocks and should always dive within their limits. The depth of the site is manageable for various skill levels and suitable for both scuba diving and freediving.
