Borra Guhalu (Telugu; ‘borra’ = bored into the ground; ‘guhalu’ = caves) was first discovered in 1807 by William King of the Geological Survey of India.
Nearby live the tribal communities of Jatapu, Porja, Kondadora, Nookadora, Valmiki, etc. According to them, the cave is a dwelling place of Lord Shiva’s and has a shivalingam.
Above the lingam are stalactite, which are seen as a cow’s udder by the locals, from which water percolates down. From these caves originates the Gosthani river, which empties itself into the Bay of Bengal.
During the construction of the DBK railway line and the Borra Railway Station, these caves were rediscoverd. One day, due to a heavy downpour, locals advised the railway workers to take refuge under a raathi godugu (stone umbrella). They led the workers to these caves, which were revealed after cutting of bushes.
The caves, believed to be 150 years old, are said by the locals to lead to the Bhadrachalam Temple. However, people do not venture too far into the caves.
Since then, the caves, located in the Ananthagiri Hills of Araku Valley, have become a major tourist attraction.
