The Sultiniye Thermal Spring and Mud Baths can be found on Lake Koycegiz. You can only access them by boat from either Dalyan or Koycegiz itself. They say the mud has therapeutic properties that can cure all types of skin problems and they say even gastric problems, as well as making you look 10 years younger. You can go and cover yourself in the therapeutic mud, then sun bake it on for as long as you like before washing it off in the sulphur pool. Although a little rough on the nose, you will walk away with your skin feeling silky smooth. After your covering of the sticky stuff, why not take a dip in the Sultiniye Thermal Spring. Again said to have healing powers over ailments like pains, rheumatism and arthritis. These springs date back to ancient times where it is thought that the ancient Kaunos people used these baths and the remains of their dwellings is found under Lake Koycegiz.
