Sivas Altınkale

Sivas province is home to the Altınkale Travertines, located in the Sıcak Çermik thermal area. These travertines are one of Türkiye’s significant geological and hydrogeological formations. The region attracts attention with its yellow-hued travertine terraces, formed by thermal waters rich in limonite and hematite minerals. Altınkale exhibits structural similarities to the Pamukkale travertines in Denizli and covers an area of approximately 40,000 m².

Altınkale Travertines were formed as a result of hydrothermal activity associated with the mineral-rich thermal waters of Sıcak Çermik. The temperature of the thermal water in the region is approximately 48°C and is characterized by high concentrations of limonite and hematite. These minerals interact with dissolved sulfur and other elements in the water, producing the travertines’ distinctive yellowish hue. The travertines are arranged in stepped pools on the surface and have been shaped by geomorphological features and tectonic elements. These characteristics give Altınkale the qualities of an open-air geological museum.

The Altınkale travertine area consists of 21,000 m² of travertine surface and 19,000 m² of recreational space. The thermal waters constitute an important hydrogeological resource due to their high mineral content and heat capacity. The presence of limonite and hematite minerals in the chemical composition of the water plays a fundamental role in travertine formation. These minerals, in combination with calcium carbonate precipitation, determine the travertines’ durability and unique coloration.

The environmental structure of Altınkale is supported by the density of thermal springs and recreational areas designed to harmonize with the natural landscape. The region hosts numerous thermal hotels and tourism facilities, making it increasingly attractive to both local residents and tourists. Additionally, tectonic movements and morphological structures in the area enhance the geological diversity of the travertines and enrich their interaction with the natural environment.

The Altınkale Travertines are located approximately 24 kilometers from the center of Sivas city, within the Sıcak Çermik spa area. The region is easily accessible by road. Planned and developed as a thermal tourism destination, this site significantly enhances Sivas’s tourism potential. Furthermore, surrounding recreational areas offer visitors extensive amenities including tent camping and bungalow accommodations.
