Araku Valley Experience: Very nice location, Good weather. Local peoples are very nice and good as well.
Food, sight-seeing and shopping: Food in the Ushodaya hotel is ok. Bit costly. Do not try an idly its very salty. the sight seeing aroung araku and bora guhala is very good. Do not missed to have bamboo chicken - costly but worthy. try to bargain and get 1kg for Rs. 450 or 1/2 kg for Rs. 200.
Activities & things to do: Do not miss to see katakki waterfalls and borra caves, The kirandul express from vizag to araku passing through atleast 50 caves is awesome.
