Rogiolo Bay is a nearly hidden anchorage situated midway between Torre del Romito—a promontory famous for Sonnino Castle—and a small hill overlooking the sea. The bay was formed naturally at the mouth of a small stream of the same name which, unlike other waterways of this type with narrow beds, carries water year-round thanks to a small spring upstream.

The origin of the name of this stream—and thus of the bay—refers to the local term for the green lizard. Due to its marine characteristics, this small cove is ideal for free divers: the crystal-clear water allows for extended observation of the underwater fauna, and the absence of hazards and difficulties makes it possible to reach two small caves and experience the sensation of swimming beneath the hill.

The seabed is rocky all the way to the shore where the stones become smaller, but there is easy access to the shore thanks to a ladder from the lido of the same name present at the foot of the promontory.

Right at the mouth of the creek, in fact, there have been Rogiolo baths since 1961, winners every year of the Blue Flag title for the quality of the water in front of the establishment.

This is a beach resort that is also equipped for people with disabilities, featuring fine gravel and a small sandy area where you can rent umbrellas, lounge chairs, chairs, and cabanas—some of which are located on concrete terraces and others on a beach of small pebbles. Behind the beach club are a bar, a restaurant, and a pizzeria. Fortunately, there is also a section of the beach that is freely accessible, allowing visitors to enjoy this small stretch of sea.

This bay, which has no moorings, is well sheltered from the swell thanks to the protection the Sonnino promontory provides from the mistral. From here, access to the anchorage is via an easy concrete walkway along the rocks, using the path leading down from the La Baracchina restaurant, which connects Rogiolo Bay to the Quercianella marina. There is also a road, owned by Ferrovie dello Stato, that is not accessible to cars; however, drivers will still have to walk a few hundred meters.

About 200 meters to the south, along the same concrete promenade, is the small port of Quercianella-name of the locality in the Livorno area where this portion of the coast is located.

On the north front of this marina, there is also a small beach with a saltwater pool obtained by arranging an ad hoc stone barrier, which is particularly suitable for children to play without risk
