Getting to the Centre for Earth Sciences at IISc
IISc is 7 km away from the main railway station and bus stand (commonly called Majestic, though the official name is Kempe Gowda Bus stand). You can avail an auto. If you do not have any luggage, you can take a local bus from Majestic (use the over bridge/subway) to cross to the local bus stand. Go to platform 23/24/25 and take any of the 252, 271 series buses. The frequency of the buses is one per min during peak hours, one per five min during non-peak hours and one per ten min during odd hours (11 pm — 5 am).
IISc is about 35 km from the airport (Kempe Gowda International Airport). One could take either a prepaid taxi (Mega cabs, Meru, Airport taxi etc.) or the Vayu Vajra bus service, operated by Bangalore Metropolitan Transport Corporation (BMTC), which runs from the airport to various areas in Bangalore city every 15 minutes. The bus to IISc is infrequent (every hour) but buses to Mekhri circle are available every 10 min. You can get down in Mekhri circle (2.5 kms from IISc) and take an auto.
Ask for Tata Institute (that’s what IISc. is commonly known as); that’ll get you to Prof. CNR. Rao circle on your map. If that doesn’t work, you should ask for Yeshwantpur circle or Yeshwantpur bus stand. From Yeshwantpur circle, follow National Highway Four east toward Prof. CNR Rao circle. You can also ask for the Malleswaram 18th cross bus stand and then walk down to Mariamma temple circle in less than 2 minutes. This place is very close to that marked as JN Tata Auditorium in the map.
