Tada falls or Ubbalamdugu Falls is in Tada mandal of Nellore district in India. It is situated on the border of Tamil Nadu and Andra Pradesh. It is situated around 95 km from Chennai.
The ideal time to visit Tada is between August - December when the sun is a little less intense. The worst time is March - June - you'd probably melt before you make it back Chennai. We went in the first week of March, and were very lucky it had been raining the past few days. That made the weather very pleasant and the heat was far more bearable.
