ABOUT MAJULI: Located on the river Brahmaputra in Assam in north east India, Majuli has the distinction of being the biggest river island in the world. The island is formed by river Brahmaputra in the south and the Kherkutia Xuti joined by the river Subansiri in the north. The island, located 1,100 km away from the mouth of Brahmaputra, had an area of 1256 sq km in 1991. Continuous soil erosion has reduced the island to 875 sq km. Majuli was also short listed for consideration for UNESCO World Heritage status. Mājuli has been the cultural capital of Assamese civilization since the 16th century. The island was under the rule of the British until India gained independence in 1947. The main village is Namghar, where villagers gather for important events, prayers and festivals. In Majuli, you can see and feel nature at close quarters. It is home to many migratory birds.
