Majuli in the Brahmaputra River in north east India covers an area of around 880 km² (340 miles²). Due to the frequent flooding of the Brahmaputra Majuli suffers heavy erosion. In the last 30-40 years it is estimated that it has lost around one third of its area. Majuli means ‘the land between two parallel rivers’.

The population of Majuli comprises the tribals, non-tribals, and the scheduled castes. The island has 144 villages with a population of over 150,000.

A wetland, Mājuli is a hotspot for flora and fauna, harbouring many rare and endangered avifauna species including migratory birds that arrive in the winter season

The only season you should consciously avoid while planning a trip to Majuli is the summer season. The intense heat and nauseating humidity is quite unbearable at times. Winter offers a very cool climate which would enable you to enjoy the natural vistas without much ado. The monsoon is also a great time to visit this island as the heavy rainfall brings life back to the vegetation and the area in general after the oppressive summer heat waves
