Even though there is not much to do in Guwahati, I did enjoy the peace and quiet here after having experienced the noise and chaos found in other parts of India for the previous several months.
People come to Guwahati in order to organise their expedition to Northeast India or apply for their permit to visit Arunachal Pradesh. it's only when you're actually here that you can get the best advice about travelling there alone. Guwahati is also where you should do your laundry, withdraw money and relax before heading off to explore Meghalaya, Assam, Nagaland, Manipur, Tripura, Mizoram or Arunachal Pradesh.
When I was in this city during my trip to India, I met an English couple and two Americans and ended up sharing a jeep with them through some parts of the Northeast. I also discussed what I'd learned about India's "Seven Sisters" with them. There are not many tourists here. So you really can't miss the ones there are.
