Araku Valley - located around 100 kilometers (62 miles) northeast of Vizag (Visakhapatnam) is not one of the most visited tourist destinations in India. Here, you can really experience the local life among the beautiful rolling hills of the valley. It's like being teleported to a different world and time.Borra Caves are situated in the Araku Valley. British geologist William King discovered this million years old cave in the year 1807 and it has been a tourist favourite ever since. Breathtaking hilly terrain, beautiful landscape, semi-evergreen moist deciduous forests, and wild fauna of the Borra Caves are a visual feast. A marvellous creation of nature, the caves were formed when river waters flow through a limestone area and the calcium carbonate turns into calcium bicarbonate, which is easily washed out by the running water.The most striking feature of the caves is its exquisite variety of speleothems ranging in size and irregularly shaped stalactites and stalagmites. Borra Caves are deemed to be among the largest in the country and are perched at a whopping elevation of about 705 metres. They are basically karstic limestone structures extending to a depth of 80 m and are considered to be the deepest cave in India. The combination of sunlight and dark conjures amazing dancing shaped in the depths of the Borra Caves which is a sight in itself.
