Borra Caves are situated ninety two kilometers away from Visakhapatnam. The Borra caves open with almost seventy five meters on vertical plane and one hundred meters on horizontal plane. On an area of one square kilometer, the Borra caves are situated, where the river Gosthani has its origin and flows through the district. The British geologist, William King discovered the Borra caves of million years old in the year 1807.

The Borra caves are surrounded by beautiful landscape, amazing hilly terrain, moist deciduous semi-evergreen forests, and wild flora and fauna which attract people from all corners of the world to enjoy its natural beauty.

There are several legends regarding the discovery of the Borra caves being narrated by some Indian tribal people who stay close to the caves. These tribes include the Porja, Nookadora, Kondadora, Valmiki, Jatapu tribe, etc. One of the most popular legends is that a cow, which is grazing over the caves, suddenly dropped sixty meters inside the earth. While looking for the lost cow, the cowherd discovered the caves. The cowherd noticed a stone inside the cave resembling a Lingam, which he understood as the Lord Shiva who saved his cow. The villagers believed in the sayings of the cowherd and since there was a temple for Lord Shiva constructed outside the cave by them, people visit the temple to pray the lord and also the cave to look at the Lingam.

There is also another legend which says that the Shiva Lingam, a phallic representation of one of the Hindu Gods, Lord Shiva, is discovered deep inside the caves and on the top of which a stone image of a cow is there. It is deduced that the udder portion of this cow is the origin of the Gosthani or the cow`s udder. The river originating from here flows through the state of Orissa before emptying into the Bay of Bengal. The formation of stone images of the Borra caves is a long drawn natural process.

Calcium carbonate present in limestone reacts with humic acid present in water and dissolves the minerals breaking the rock gradually. The recurrent flow of water over a longer period results in the shaping of caves. Stalagmites are created due to water leaching from the roof which possesses calcium bi-carbonate and various other minerals from mounds. In the same way stalactites are formed and due to their different shapes local people and tourists have provided different names to them. There are various types of formations to be seen of the stalagmites and stalactites as Shiv-Parvati, Rushi`s Beard, Mother-Child, Human Brain, Tiger, Crocodile and Cows udder.
