Then we visited Varahi Underground project, a hydro-electric power station built Underground. We will have to get prior permission to enter here from the govt. It's worth a visit, specially if you are an electrical engineer or a mechanical engineer. Very beautiful and educational.
You won't be allowed to take photos. We weren't either.
Then to sum up the day, we visited Kundadri hilltop for a perfect, picturesque sunset. Small vehicles do go till the top, but buses can't. Cars, TTs and mini buses do go up there. The sunset, cool evening breeze and the peaceful environment refresh you completely. A definite visit for anyone travelling around there.
