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.
Site Conditions
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

Freediving
Not a practical freedive target beyond the very shallow shoal.
Snorkeling
