Although Silchar is a very small town and lack of very good transportation does not much affect a tourist, it should be mentioned here that the town has no private Taxi system. Either you take a bus, which is generally not at all comfortable, or hire an autorickshaw or the most common transport system, the peddled riskshaws.
clay during rains
The roads (the broken parts where the mud comes off), becomes full of clay during the rainy season so that while walking on the roads, you will have to look more downwards than towards what is in front of you.
Powercuts - OOOOOF
Although I love my former hometown, one thing I hate about it, is not the floods, not the dust, nor the bumpy roads, but the frequent powercuts. There's normally no power for about 5 - 6 hours a day on average.
Like many places in Assam, Silchar is also very prone to having floods. Avoid the place during heavy rains in Manipur, Mizoram and Meghalaya. If there's rains in Assam, that's not a problem. The floods are generally the result of heavy rains in these three neighbouring hilly states from which water flows down to the Barak river flooding Silchar town.
