The Insuyu cave, located on the highway from Antalya to Burdur, is the first cave system officially opened to tourism. The cave system contains many lakes. The biggest of those, "Büyük Göl", is the largest known underground lake in Turkey.

The Insuyu cave is a natural cavern formed by the dissolving of limestone rock by the seepage of rainwater through natural cracks from the surface. Rainwater takes carbondixide from the air and forms carbonic acid. This acidic rain water seeps into the caverns, dissolving the limestone and thus enlarging the cavern.
The age of the caverns are not precisely determined, although it is assumed to be between 500.000 and 1.000.000 years, as most of the other carstic cave systems in Turkey are.
Feel free to log after AFTER sending the answers the following questions to my profile email address
- Explain how the columns inside the cavern are formed
- What is the approximate height above sea level
- How many distinct lakes are in the caves?
