Island Location
There are 3 large (Marmara, Avşa, Paşalimanı) and 9 small (Ekinlik, Koyun, Mamalı, Hasır, Pale, Fener, Asmalı and Paşalimanı Bay) islands in the southwest of the Marmara Sea. These islands, which are named Marmara Islands, are in terms of structure and shape. They are the extension of the Kapıdağ Peninsula in the Marmara Sea 4 As a result of the rise of the sea level and the flooding of the low parts at the end of the time, they have taken their present shape by separating from the mainland Kapıdağ Peninsula and each other.The depth of Avşa Island with Marmara and other islands is 16-35 meters Since only the land that joins Ekinlik Island is at a depth of 1-4 meters, it is possible to follow this connection in calm weather.The length of the island is 9 km and its width is 4 km. Total area is 36 km².

Natural Structure
The island is generally covered with sandy soils consisting of granite and granodiorite bedrock The rate of sand is quite high Granite stones are scattered almost on the surface texture of the island The wide alluvial coastal plain is located in the western part and a partly wooded part is located in the eastern part of the island’s villages (Türkeli and Yiğitler Villages)

Flora
Trees have been cut due to the low agricultural culture and widespread viticulture Viticulture is very developed Most of the island is filled with vines.
