# Sultaniye Hot Springs (Sultaniye Kaplıcaları) — Healing Thermal Mud Baths

Sultaniye Hot Springs is a historic mineral spa on Lake Köyceğiz, offering therapeutic mud baths, hot radon pools, and direct lake access for cold plunges.

This unique balneological complex, highly regarded since Roman times, is located at the foot of Mount Ölemez on the southwestern shore of Lake Köyceğiz. Visitors travel here for healing mineral waters and famous therapeutic mud baths.

The Wellness Ritual: Mud, Thermal Springs, and the Lake

The mineral waters of Sultaniye are rich in radon, sulfur, calcium, and iron. The water temperature in the thermal spring pools stays consistently around 39–40°C. The traditional wellness ritual is as follows:

1. Mud Baths: Visitors cover themselves with thick medicinal mud in dedicated open-air pools and wait 10–15 minutes for it to dry under the sun. The mud is believed to revitalize the skin and soothe joints.
2. Shower: Once dry, the mud is rinsed off under cool showers.
3. Thermal Pools: Next, bathers soak in the covered domed pools filled with hot mineral water for deep relaxation.
4. Lake Köyceğiz: Finally, visitors step onto the wooden piers to take a refreshing plunge into the cool waters of Lake Köyceğiz. This hot-to-cold temperature contrast revitalizes the body.

Important Notes

The water at Sultaniye has a strong, distinct smell of hydrogen sulfide (rotten eggs) due to its high sulfur content. The complex is operated by the Köyceğiz Municipality, keeping the facility entrance and cafe prices highly affordable.
