Mannanur, which is around 120 km from Hyderabad, is the place where the Nallamala hills start. After 60-70 km of drive through the forest you'll reach Eegalapenta. From there, it becomes difficult to drive as there are numerous hairpin bends and a kilometer of the stretch has lot of potholes. You can have a good look at the Srisailam Dam from there.
