it's a bit of travel..not far though. under 10kms i guess. if you don't want to be taken for a ride by the auto guys, call a cab.
As Dheeraj has mentioned above, it is under 10 kms from the station and you can hire a pre paid auto from the station itself. Bangalore Cantonment (BNC) is the nearest station to Benson Town and trains going to Bangalore City station from Chennai side stop here. So please check if your train passes through this station.I need to,go to a place called Benson Town.. How will I proceed to this place from yeshwantpur railway station??
