About Secca del Trimelone
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.
