Chakrashila Hill was first declared as reserve forest in 1966 and on 14 July 1994 it was recognized with the status of sanctuary by the Government of Assam.[5] A local environmental activist group, Nature's Beckon played a vital role for this recognition.[6]
Location
The sanctuary covers an area of 45.568 km2 (4556.8 hectares). It is around 6 km from Kokrajhar town, 68 km from Dhubri town and 219 km from Lokpriya Gopinath Bordoloi International Airport, Guwahati. The sanctuary is mainly a hilly tract running north–south and there are two lakes (Dheer Beel and Diplai Beel) on either side, which are integral to the eco-system of the sanctuary. The lower hilly reaches are covered with sal coppice regeneration while middle and upper reaches are covered with mixed deciduous forests. The sanctuary has some tourist accommodation facility at Choraikhola, Kokrajhar and also provides facilities for bird watching, forest trekking, and wildlife and nature photography
