From Scoglitti to Pozzallo, the Ragusan coastline is approximately long. Along the Ragusan coast are many fishing villages such as Kaukana, Punta Secca, Marina di Ragusa and Marina di Modica. The Hyblaean Mountains are dominating the north of the province and its highest peaks are Monte Lauro, Monte Casale and Monte Arcibessi. The rivers of the province are the Irminio, Dirillo and Ippari and the only lake in the province is the Lago di Santa Rosalia along the course of the Irminio river. The skyline of Ragusa is punctuated by the towers, domes and cupolas of the many churches for which the province is known. The area is mostly unspoilt, as during the 19th century and early 20th century there was large migration from Ragusa to the more prosperous areas of Italy and abroad.
