Be collected from your accommodation in Marmaris at 8:30 AM and travel 45 minutes to Koycegiz. When you arrive, board your riverboat and enjoy the breathtaking beauty of Koycegiz Lake. Visit the thermal springs and mud baths, which provide secret health benefits. The waters are rich in blue-hydrogen and radon, which relieve joint pain and aid the musculoskeletal system. In the vicinity of the village of Dalyan, there are 12 springs with different chemical compositions of water. Continue your tour and sail through the narrow ducts of the river. See rock tombs built between the 5th and 4th centuries BC during the oligarchy of the ancient city of Kaunos. They are the best examples of Lycian graves in the territory of Turkey. Return to your boat and be served a mouth-watering meal. The final stop will be at Turtle Beach. The unique sandy Iztuzu beach is where Caretta-Caretta turtles lay their eggs. The beach is a natural reserve and is under state protection but you can swim in the freshwater lake beside the beach. If you are lucky, you will see turtles on the beach. In the evening, from May to October, the beach is closed. Be dropped off at your accommodation around 7:30 PM.
