Prasonisi is the Greek word for «green island». During summer time, and when water levels are low enough, this island is a peninsula attached to Rhodes. During the winter time, and when water levels are high enough, Prasonisi becomes an island. The southernmost tip of Prasonisi contains the Prassonissi Lighthouse. The closest Greek village is Kattavia; however, there is a purpose-built settlement on Prasonisi that contains motels, convenience stores, restaurants, and windsurf rentals which are open seasonally. Near Prasonisi is Vroulia, an ancient settlement that contains an old mosaic tiled floor.
