From Airport, one can either take a bus (not recommended) or a shared taxi). There would be six passengers, two in front and four at the backseat. Charge for each person for one way travel is Rs. 70. For going to the airport, the taxis can be found outside the Airport office (Geetanjali hotel) and while coming back from airport, they can be found just outside the aerodrome.
Another option are the autorickshaws. Apart from some specific places like the Silchar Medical College, Silchar Polytechnique, etc. there are no fixed route autorickshaws. So you have to reserve one (means you have to contract for a lumpsum money and you will be the only passenger). Fare for the minimum distance is Rs. 20 to Rs. 25, and keeps on increasing as the distance increases. but Silchar autorickshaws are much comfortable as compared to other towns
Well if you are in Silchar, you have got to depend on rickshaws. There's nothing more dependable. The roads are full of rickshaws, rickshaws and rickshaws. Just negotiate the price before getting on it. There generally three standard prices, Rs. 5 for a location very near, Rs. 10 for a little far off distance and Rs. 15 if it is too far. But that's anyhow cheap.
Anybody who goes to Silchar must consider one way journey by the train from Guwahati. The train track from Lumding (six hours from Guwahati) to Silchar is beautiful and an unforgettable experience. (Please see my things to do tips on it). Its a meter gauge train. But be sure to carry your food as foods are generally either not sold on way or are not very good for consumption
The best way to go to Silchar is by Aeroplane. It's hasslefree as one does not come across bad roads. Flights are regularly flown from Kolkata (generally early morning), also flights are there from Imphal (Manipur) and Aizawl)
