Conero’s Two Sisters beach, a promonitory located on the Adriatic coast of Italy, consists primarily of large limestone sand grains formed from marine sediment during the Jurassic period. The coastal area beaches are backed up by limestone cliffs and associated landslides. The “Due Sorelle” (Two Sisters), two white rock stacks, are a prominent feature emerging from the deep blue and turquoise sea. Le Due Sorelle beach is accessible only by sea.
Geographic Overview
The Conero Peninsula is a stunning coastal region in the Marche region of central Italy along the shores of the Adriatic Sea. Sea and wind erosion have sculpted the Conero coastline, creating coves, gulfs, and beaches. The promontory itself is the core of the Conero Natural Park, and the cliffs provide a dramatic backdrop to the coast.

A rare dark sand grain is occasionally present on Two Sisters Conero Beach where sand is comprised primarily of large smoothly worn white and off-white limestone pebbles with occasional angular grains that have not yet been polished by the wind and sea.
Smoothly worn white and off-white large and small sand grains with occasional angular edged grains are in this sample.
This view of light and an occasional dark sand grain demonstrates varying degrees of roundness with an occasional dark sand grain present on a predominantly limestone beach.
This lower magnification view captures variably sized smooth white and off-white sand grains along with a prominent rough angular surfaced rectangular sand grain not yet worn smoothly by wave and wind action.
