Tanguar Haor, Wetland basin in Sunamganj district, Bangladesh
Tanguar Haor is a large wetland basin in the Sunamganj district of northern Bangladesh, made up of 51 interconnected swamps and canals. The landscape shifts dramatically between seasons: dry fields and green land in winter, open water stretching to the horizon during the rains.
The area has been used for fishing and farming by local communities for centuries, with its seasonal floods shaping the way people lived. In 2000, Tanguar Haor was designated a Ramsar wetland of international importance, giving it formal protection.
During the monsoon, fishermen work the canals and ditches in small boats, following a rhythm tied closely to the water's rise and fall. Watching them cast nets or move between channels gives a clear sense of how daily life here is shaped by the seasons.
The best time to see the flooded basin from a boat is from mid-July to early September, while December and January bring the most migratory birds. The water channels can be hard to navigate without local knowledge, so hiring a guide or a boat with a local driver is a good idea.
In the middle of the haor sits a small hill called Bil Hatirgata, which emerges from the water in winter and offers a wide view over the surrounding land. On clear days, the hills of Meghalaya across the border in India are visible from there.
