Kadıköy is located on the Anatolian side of Istanbul. It falls in the middle of the city of Istanbul, to the east of the mouth of the Bosphorus in the Marmara. To the east, it is bordered by the district of Maltepe, to the west by the Bosphorus and the Marmara Sea, to the north by the districts of Üsküdar and Ataşehir, and to the south by the Marmara Sea. Kadıköy is built on six hills. These hills from east to west are Göztepe, Fikirtepe, Acıbadem, Altıyol, Cevizlik (Küçük Moda), and Koşuyolu. Fenerbahçe Park, Göztepe Park, Özgürlük Park, and the green areas extending along the coast are the most important active green spaces. Kadıköy has a coastline of approximately 21 km extending from Haydarpaşa to Bostancı in a southeast direction.
