About the location (from Wiki):
The Borra Caves, also called Borra Guhalu in Telugu language (‘Borra’ means something that has bored into the ground and ‘guhalu’ means caves), are located on the East Coast of India, in the Ananthagiri hills of the Araku valley (with hill ranges elevation varying from 800 m to 1,300 m) of the Visakhapatnam district in Andhra Pradesh. The Caves, one of the largest in the country, at an elevation of about 2,313.0 ft, distinctly exhibit a variety of impressive speleothems ranging from very small to big and irregularly shaped, stalactites and stalagmites. The Caves are basically Karstic limestone structures extending to a depth of 262.5 ft (considered the deepest cave in India). In 1807, William King George of the Geological Survey of India discovered the caves.
