Capo Berta represents the western boundary of the Gulf of Diano, while east is Capo Cervo. In the top of the promontory are the remains of a circular masonry fortress dating back to the 14th and 15th centuries, the Torre dell'Alpicella.

Capo Berta is a SIC - Site of Community Importance - both marine and terrestrial. The Habitat Directive (92 / 43CEE) is intended to "contribute to the preservation of biodiversity through the conservation of natural habitats..."

Capo Berta's marine environment has a high biodiversity. Environments with higher biodiversity are more fragile and therefore struggle to regenerate even if the amount of available solar energy and climate stability are positively affecting. The coastal seabed between Oneglia and Diano Marina is of predominantly sandy nature and features stretches of grassland meadows, predominantly of Posidonia oceanica.

SIC terrestrial
The SIC territory is part of the current route of the "Aurelia" road and the south-facing sea.
It is important especially for the conservation of coastal habitats, it has aspects of cliff vegetation, gariga (rosemary, thyme, broom, dwarf palm tree, etc.), stain and ferns of Aleppo pine pine (Pinus halepensis).
There are endemic species such as the corded stem (Limonium cordatum) and the bell-ring of Savona (Campanula sabatia), a priority species, as well as some orchids have been reported.
