At Sultaniye people come to bathe in water at 40ºC, rich in calcium, sulphur, iron, nitrates, potassium and other minerals.
Close to this, there are spots to take mud baths, right at the place where the lake flows into the Dalyan river.
Getting there is mainly done by tourist boats that use 30 minutes to get to the place. There is an admission fee at 4TL.
