Amchang Wildlife Sanctuary protects forested hills on the eastern edge of Guwahati, forming one of the city's important green buffers. The sanctuary is associated with elephants, birds, and the rougher landscape that begins beyond the urban sprawl.
It is not as straightforward a visitor site as the temples and museums in town, so check local access and conditions before going. For nature-minded travellers, though, it shows how close Guwahati remains to Assam's wild hill country.
