 The coastal strip, made of recent marine deposits, is edged by a fine sandy beach, 15 km long and up to 200 metres wide, interrupted only by the mouth of the rivers and gently shelving towards the sea.Along the coastline there is a low sandy cliff, created by sea rise around 4000 B.C., partly conserved north of Rimini, between Rivabella and Bellaria-Igea Marina, at a distance of about 1,300 metres from the coast.Rimini's territory, for its geographical position and its climatic features, is situated on the edge between the mediterranean and the central European phytoclimatic zones, and thus it represents an environment of notable naturalistic value.
