We are Senior Citizens from Chennai and we used the Public Transport like Train and bus.We usually go and have darshan of Thayaar before going to Tirumalai. We took the 16057 Saptagiri Express from Chennai Central and got down at Renigunta on 21st November at 8.55 A.M. The usual A.P.S.R.T.C. buses plying from Renigunta(Service Road near Renigunta Railway Station) to Tirumalai were not there.We usually take these buses upto Ramanujar Circle -Bliss Hotel stopping and from there take buses, share auto to Sri Alamelu Mangapuram. We save almost an hour and half as we do not go upto Tirupati station and take a bus to Sri Alamelu Mangapuram.. What is the best way to go from Chennai to Tirupati for two seniors to do darshan? Thanks.
