Insuyu Cave Located 13 kilometers from Burdur to Antalya, Insuyu Cave is a horizontal cave that stretches for a total length of 597 meters. The cave sits about 1200 meters above sea level and is situated on the northeast side of the Western Taurus mountains. It is comprised of limestone geology and is believed to have been formed thousands of years ago due to the accumulation of limestone deposits. The cave is home to 9 lakes, both large and small, which are found within the caverns that open in various directions, and have a constant stream of cool, fresh air flowing through them. The melting of limestone and the erosion inside the cave over time led to the creation of stalactites and stalagmites. The water inside the cave is believed to have curative properties for diabetes and stomach diseases, particularly when mixed with medicinal herbs. Insuyu Cave offers visitors an opportunity to explore and marvel at the natural beauty of this underground wonder.
