The Sundarbans is basically a huge forest in the coastal region of the Bay of Bengal and it's spread across India and Bangladesh.
It's got the total area of about 10,000 sq.kms. of which 6000 sq.kms belongs to Bangladesh and remaining 4000 sq.kms belongs to India.
I present just a few pics from the Sundarban Tour.
I'll be making a full-fledged post on this tour in a later time.
