A unique blue for these three beaches of Sirolo. The beach of San Michele can be reached along the avenue of Parco della Repubblica, and communicates with the adjacent Spiaggia dei Sassi Neri. This name derives from the dark rocks that can be glimpsed in the seabed and give the waters particular dark shades.

Spiaggia Urbani can be reached by descending from the street next to the Cortesi Theater; It is a beach between a cliff of white rock and a natural cave.
