İnsuyu Mağarası is at Mandıra village, 900 metres east of the Burdur-Antalya road at its thirteenth kilometre.
It is a horizontal cave 597 metres long, and the provincial directorate counts it among the first caves in Türkiye opened to tourism.
Its age is an estimate rather than a measurement: from the way the stalactites and stalagmites formed out of limestone deposits, the directorate reckons the cave took shape thousands of years ago.
