Lake Garda boat wall with a deeper cave section.
A guided boat run is the practical way to dive the shoal and wall, especially if you want the cave section.
Secca del Trimelone is a Lake Garda boat dive off the island of Trimelone, where a shoal falls into a steep freshwater wall and then a deeper cave section. It works well for open-water divers on the shallower profile and for experienced or technical teams who want a colder, more demanding lake dive.
Conservative baseline from public research. No community dives logged yet.
Depth range, seasonality, and planning context.
Reported Depth
7m - 48m
Depth Note
The shoal tops around 7m, the wall drops to 40m, and a cave section reaches 48m.

Late spring through early autumn, with cold-water protection useful year-round.
Typical Conditions
Freshwater shoal and wall profile with clear water on good days, colder water below the thermocline, and a deeper cave section that rewards careful planning.
Hazards, restrictions, and access requirements.
Key Hazards
Safety Notes
Use a local guide, keep buoyancy tight on the wall, carry a light for the cave, and plan for cold water below the shoal.
Access Restrictions
Boat access is the normal approach, and the deeper cave section is only for properly trained technical divers.
Legal Notes
Follow local lake rules, boat briefings, and any site limits set by the operator.
Community notes to help plan your visit.
Scuba Diving
Best for scuba. Open-water divers can enjoy the shoal and wall, while experienced and technical divers can continue into the cave.
Freediving
Not a practical freedive target beyond the very shallow shoal.
Snorkeling
Not a snorkel site.
