Key Dive Site Facts
Dive Site Overview
Secca del Trimelone emerges from a substantial freshwater body, presenting a distinct topography; its name comes from a nearby bunker island. Diving begins at a vibrant shoal top, roughly 7 meters below the surface.
A guide line typically directs divers towards a dramatic steep wall, which plunges impressively, reaching recreational limits around 40 meters. This vertical feature doesn't end there; its deeper sections extend considerably further, inviting exploration by qualified individuals. For those with appropriate technical certifications, a fascinating cave system becomes accessible, with its passage concluding around 48 meters.
Distinctive geological structures, alongside the islet's proximity, contribute to this site's compelling underwater landscape. It welcomes both Open Water divers to its shallower regions and more experienced explorers to its greater depths, offering a range of challenges.
Expect varied sights across its extensive vertical profile, from the illuminated shoal to the darker recesses of the wall and cave. Navigating these sections requires careful buoyancy control and an awareness of the changing light conditions. Each descent offers a rich experience for those prepared for its unique demands.
Best Time to Dive
Surface conditions at Secca del Trimelone are often most inviting from May through September, aligning with the external recommendations for the best diving season. During these months, average air temperatures range from 17.2°C (63°F) to 25.1°C (77°F), making boat entries and surface intervals comfortable. However, dive scores indicate excellent conditions year-round, with high scores even in cooler months when air temperatures are lower, dropping to 6.6°C (44°F) in January. Rain levels remain consistently low throughout the year, typically between 1.8mm and 6.9mm per month, minimizing its impact on dive plans. While specific water temperatures are not consistently reported, divers should anticipate cooler conditions at depth even during summer, a common characteristic of lake diving.

Dive Experience & Conditions
Anticipate a distinct sensory impression when exploring Secca del Trimelone, transitioning from the brighter shoal top to the cooler, more subdued light of its deep walls and cave. Visibility in this freshwater location can be quite good, allowing for clear views of the geological structures. This aquatic environment often presents different buoyancy characteristics compared to saltwater, necessitating minor adjustments from divers. Moving along the steep wall, divers might notice subtle changes in currents; these are generally manageable but vary depending on conditions. The deeper sections of the dive, especially within the cave, necessitate proficient torch skills and a strong awareness of depth and gas management, due to the decreased natural light and potential for cooler temperatures. Divers should prepare for thermal comfort as they descend.
Dive Difficulty & Safety Guidelines
Approaching Secca del Trimelone, divers should always prioritize adherence to general safety protocols, even if specific hazards are not consistently reported. Always dive with a buddy, and considering an experienced guide is prudent, especially if unfamiliar with the local aquatic conditions. Due to the significant depths encountered, which can extend to 48 meters, proper training in deep diving is essential. Technical divers exploring the cave system must possess the appropriate certifications and rigorous gas planning. Carrying a suitable wetsuit or drysuit, a hood, gloves, and a reliable diving torch is recommended to manage the potentially cold water at depth and effectively navigate darker areas. Checking for local diving permit requirements before your visit constitutes a crucial preparatory step.
