I live in a medium sized North-East-Indian state called Assam, in the capital city called Guwahati. I am usually home in the summer or during Christmas/New Years. If you want to explore North-East India, Guwahati is a great place to start because it links the rest of India to the North-East. From Guwahati, you can visit the states of Meghalaya, Arunachal Pradesh, Mizoram, Nagaland, Manipur and Tripura. You can also visit the world-renowned Kaziranga National Park, which is about five hours from where I live. The National Park is one of the only places in the world you can see a one-horned rhinoceros. Plus there is the added attraction of going on elephant rides :D
However, the National Park is only in season during the winter!
