The cliffs of the San Bartolo emerges from low beaches
of Romagna and Marche as a succession of undulating spurs vellecole and degrading
to the sea, interspersed here and by sheer cliffs. The shares of most high peaks close to the cliff do not reach the 200 meters, but
they allow a broad view of the coast and the sea, while the cliffs are an unusual seascape for coastal sandy of Romagna and the Marche.
The cliff shows areas of high geological interest with fish fossils and rare crystals of gypsum; runs behind a beach of fine gravel
and pebbles used as a quarry until the second met the twentieth century, today protected by the Park's institution
Along some stretches of the coast have developed dense submerged meadows of Zostera marina and Cymodocea nodosa. These plants are a natural heritage of great
value and are protected by Italian law on the conservation of Biodiversity. Grasslands submerged in addition to being a real "nursery"
for many variety of fish, slow erosion and encourage the preservation of natural beaches.
