This is the largest mangrove forest in the world and not that far from Rajarhat , which was once a small village outside Calcutta. I born and brought up there and spent first 18 years of my life in Rajarhat , still I did not visit Sundarban. So it was always in my bucket list. December is always peak time to visit Sundarban, still I had no option. So I booked a 2 night / 3 day tour from local Calcutta tour company called "Chuti Chuti".
