To Reach IISc
From Bangalore international airport
IISc is about 35kms from the airport. One could take a city taxi (costs about Rs. 500, and a queue for the same is just outside the airport building). The Institute is known as "Tata Institute" to the locals and is just past Mekhri circle and on the way to Yeshwantpura (one must take a right turn at Mekhri circle). Shuttle bus service, operated by Bangalore Metropolitan Transport Corporation (BMTC), runs from the airport to various areas in Bangalore city every 15 minutes. Details of the schedule can be found here. Additional information on the airport can also be found at Bengaluru Airport
From city railway station
The city railway station is about 7 kms from IISc campus. One will have to get out of the station from platform number ONE and reach the prepaid auto stand and hire a auto (costs about Rs 60). Majestic (7kms from IISc) is the central Bus stand in Bangalore which is just opposite to the City Railway station. If one happens to reach Majestic, Bangalore by bus, reach platform number 22 from where almost all buses come to the Institute.
From Yeshwantpura railway station
The Yeshwantpura railway station is located at less than 2 km from the institute campus. One can take a 'pre-paid' auto from the counter located outside the exit gate of platform number 6. The prepaid autos shouldn't charge more than Rs. 30 and is the best deal given the options available. The landmark is CNR Rao Circle from where one would take the entry to IISc. Though the prepaid contract says IISc (Tata Institute as more popularly known) gate as the destination, the hostels and most of the academic departments are within 500 mts from the gate, and hence the auto can be requested to drop at your destination.
