The boat leaves Gosaba before the tide turns and does not touch a road again for four days. You sleep on the water, wake to the sound of the forest deciding whether to speak, and spend the light hours reading the bank for pugmarks the last tide has not taken.
This is not a safari. Nothing is fenced, baited or guaranteed. What you get instead is the delta on its own terms: creeks narrow enough to touch both banks, a watchtower at Sajnekhali, and a guide who has spent thirty years learning which silences mean something.
