Borra caves are the natural caves, that are said to have originated from the Gosthani river, which flows through these caves. The caves were created due to the flow of river over the limestone area. The pressure was exerted by the humic acid in the water on the mineral deposits and the limestone dissolved in the water. The dissolved limestone trickled down drop by drop forming the different shapes in the cave. These Borra caves spreaded over the one square km and are formed over the period of millions. The opening of the cave measures upto 100 m horizontally and 75 m vertically. The cave is filled with stalagmite and stalactite formations. Visitors have given different names to the different shapes of these stalagmite and stalactite formations such as Shiv Parvathi, Mother child, Human brain, crocodile, Rushis Beard etc. Some more interesting structures inside the cave include mushroom formation, temple, church and many more.

The caves of Borra are said to be more than 150 years old. These wonder caves were discovered by the British geologist William King Gorge in the year 1807. The local tribals inhabitating in this area have a different story to tell. They say once a cowherd lost his cow while grazing. He soon realized that his cow had fallen down. He got worried, on looking down he found 60 feet deep hole, where he saw his cow was alive and feeding on the grass deep below. This was the time when the tribal has discovered the cave.
