IISER Mohali is situated in Sahibzada Ajit Singh Nagar, which is located next to the city of Chandigarh. Chandigarh is well connected to Delhi and Mumbai by air, and to Delhi by train. If you plan to travel to Chandigarh by train then the three Shatabdi express trains are a good choice. You may consult this website for travel related information.
Public transport in Chandigarh consists of bus services. You may also hire taxis or auto rickshaws. Many cab companies accept bookings on phone, these numbers will be posted here a few weeks prior to the conference.
Chandigarh is the gateway for a large section of Himalayas and the province of Punjab. If you are planning to visit some places before or after the conference and you need our help then please let us know.
