About

Sunamganj's vast freshwater haor turns into an inland sea each monsoon. Pair houseboat nights with Niladri Lake's turquoise quarry water and winter birdwatching.

Tanguar Haor spans roughly a hundred square kilometres across Tahirpur and neighbouring upazilas of Sunamganj — Bangladesh's second-largest freshwater wetland and a Ramsar site of international importance.

In monsoon (roughly June–October) runoff from the Meghalaya hills floods the basin into an open inland sea. Hijol and koroch trees stand in the water, villages become islands, and houseboats become the only practical way to travel. Winter lowers the water and brings migratory ducks and waders from Central Asia and Siberia.

Most packages start from Tahirpur Ghat and include the Golabari watchtower, a night on the open haor, and a stop at Niladri (Shaheed Siraj) Lake at Tekerghat — a flooded limestone quarry framed by white cliffs and green border hills. Carry life jackets; sudden storms and waves (afal) are real hazards on open water.

Wear life jackets on open haor water. Niladri quarry lake is deep — non-swimmers should stay in kayaks near shore. Respect the India border zone at Tekerghat.

Culture, food & etiquette

Cuisine: Haor fish curries, dried fish, sticky rice sweets

Local boat communities often paddle out to greet houseboats — support them with fair tips, not litter.
