Eynal Termal Tesisleri is the geothermal facility complex in Simav, Kütahya province, western Turkey, associated with the Simav Eynal hot springs 5 km from the town center and known as Turkey's first thermal aquapark, combining traditional mineral spring bathing with modern waterpark recreation in a format that has attracted family visitors and wellness tourists from across the Marmara and Aegean regions. The Simav graben — the same seismically active rift valley that caused the destructive 2011 Simav earthquake — concentrates high-temperature geothermal resources beneath the town and its surroundings, making the region one of western Anatolia's most productive geothermal energy and thermal bathing zones. The Eynal thermal facilities represent the contemporary evolution of Turkey's kaplıca tradition, blending the mineral waters of Simav's geothermal system with recreational infrastructure in a region with thousands of years of thermal spring use.
