Geography
Arunachal Pradesh covers 83,743 sq. kms. (roughly the size of Austria) and is characterised by mountains. Much of the state is covered by the Himalayas, further parts by the Patkai. Its highest mountain is Gorichen Peak at over 6,700 metres. Arunachal Pradesh is bordered by Bhutan, Tibet, Myanmar and the Indian states of Assam and Nagaland, making it a unique blend of cultures and peoples. It is also an area disputed by China, which calls it South Tibet and does not recognise the McMahon line that separates the two countries. It has only been a full state of India since 1987.

Assam covers 78,438 sq. kms. (roughly the size of the Czech Republic) and is bordered by West Bengal and six of the Indian States collectively known as the “Seven Sisters''Arunachal Pradesh, Meghalaya, Mizoram, Nagaland, Tripura and Manipur (Assam itself is the 7th Sister) 'as well as Bhutan and Bangladesh. The river Brahmaputra, which is as wide as 10km in places, cuts the state in two. Majuli, the world's largest river island, covering 577 km2 and with a culture all of its own, is found in the Brahmaputra near Jorhat.

Meghalaya covers 22,429 sq. kms. (roughly half the size of Denmark) and shares a border with Assam to the North and West and with Bangladesh to the South and East. The state is also known as "Meghalaya Plateau" because it consists mainly of Archean rock formations. Due to its heavy rainfall it is characterised by rivers, gorges and waterfalls.
