Is the smallest municipality in Liguria by area, although not by population density.
A coastal village that has become a popular seaside holiday destination – it has been awarded the Blue Flag – whose origins date back to the 12th century when it was a dock on the mouth of the Aqua Sancti Laurentii, the river from which it takes its name.
Historical vicissitudes have resulted in San Lorenzo being divided into two distinct urban areas, which, if seen from an aerial perspective, give the appearance of an anchor: the area along the coast and the area in the hills, which is still particularly rural.
San Lorenzo is the starting point of the Pista Ciclabile del Ponente Ligure (Western Liguria Cycle Path), which continues as far as Ospedaletti and will probably be extended even further to the east in future.
