Orhaniye is the deepest you can go into the Hisaronu Gulf. Although by sea you would need to sail around the peninsula to get to Marmaris, by car it is actually only about 20 minutes drive. The village of Hisaronu is renowned for its natural beauty.
There is a natural spit called Kizkumu that stretches out into the bay, dividing it in two. The name originates from the legend that a girl carried sand into the sea in her skirt to form the spit in order to cross the water to reach her love. You can walk the full length of the spit right into the middle of the bay, however shoes would be recommended as the stones are very sharp on bare feet.
Drive out of the village for about 15 minutes and you will come to Turgut Koyu which is blessed with a waterfall. In the village you can visit a carpet factory and learn about Turkish carpets and rugs without being obliged to buy.
