Dibrugarh ROCKS.

Dibrugarh district is surrounded by Dhemaji district in the north and a part of Lakhimpur district i

It is the gateway to the three tea-producing districts of Tinsukia, Dibrugarh, and Sivasagar. These three areas account for approximately 50% of India's Assam tea crop, and this gives Dibrugarh its rightly earned sobriquet as the "Tea City of India". Oil and timber are the other two big industries in and around Dibrugarh.
