Tulumtaş Cave

Tulumtaş Cave is a natural underground formation located within the boundaries of the Gölbaşı district of Ankara Province in Türkiye’s Central Anatolia Region. Formed through karstic processes, this cave attracts attention not only for its geomorphological features but also for the geological traces it preserves. Various institutional studies were conducted between its discovery and opening to the public, resulting in its designation as a site of natural heritage and research value.

Physical and Geomorphological Features

Shaped by natural karstic processes, the cave is characterized by formations such as stalactites, stalagmites, columns, and dripstone pools. These speleothems emerged as a result of prolonged mineral deposition processes occurring over extended geological time periods. Its limestone (calcite) base allows for the observation of diverse morphological forms in different sections of the cave.

Geological Significance

Tulumtaş Cave draws attention not only through its physical structure but also through the geological data it contains. Studies conducted by the Department of Geological Engineering at Ankara University revealed significantly high concentrations of chromium, nickel, and cobalt in soil samples taken from the cave. These findings indicate a direct association between the cave and rocks originating from the oceanic crust. Furthermore, the formation process of the cave began with the dissolution of rocks dating back approximately 150 million years to the Jurassic Period and continued until about five million years ago.

History and Recognition Process

The existence of the cave was first identified in the 1990s by the General Directorate of Mining Research and Exploration. However, this discovery did not lead to any public regulation or conservation efforts for many years. In the 2020s, concrete steps were taken through a collaboration between the Ankara Metropolitan Municipality and the Ministry of Culture and Tourism to open the cave to visitors. During this process, the goal was to preserve the cave’s natural structure while ensuring suitable conditions for tourists.

Process of Opening to the Public

To ensure safe and sustainable visitation, various infrastructure modifications were implemented within the cave. Walking paths, safety barriers, directional signage, and lighting systems were designed to minimize intervention in the natural structure. Additionally, information areas were established at the cave entrance as part of environmental improvements.

Following the completion of infrastructure works, Tulumtaş Cave was opened to the public on 1 August 2023. The opening ceremony was attended by local officials and members of the public, during which information was provided on the cave’s promotion and conservation.

Tourism and Educational Potential

Tulumtaş Cave serves as an important ecotourism and environmental education center for the Gölbaşı district and the surrounding Ankara region. Its geological structure and natural richness offer potential not only for tourist visits but also for academic use in geology, environmental sciences, and nature education. The promotion of the cave is being carried out in a manner that contributes to the regional economy and cultural awareness.
